Juniper used to offer 100% off vouchers for five of their certifications until November, 30th and recently reverted back to 50% off. This was and is still a good opportunity to take advantage of this offer because that can save you a lot of money and increase your value in the job market if you’ve had any previous experience with this vendor. One of the main reasons I decided to put off my CCIE SP preparation for a few months was that I want to be able to work in a multi-vendor rather than just a pure Cisco environment. Networks are very diverse nowadays and it is common to see equipment from multiple vendors in the IT infrastructure as every vendor has its strengths and weaknesses. I usually laugh when someone says “Cisco is the best and I only like and work with their equipment” or “Juniper is to rule them all”. The interaction between vendors is very important and this is what I am hoping to experience and get a grip on in the next couple of months.
The certifications that are offered at a discounted price in the Fast Track program include:
JNCIA-JUNOS & JNCIS-SEC (security)
JNCIA-ER & JNCIS-ER (enterprise routing)
JNCIA-EX (enterprise switching)
First, you need to pass a free online pre-assessment exam (can be taken as many times as you want) in order to receive the voucher. The materials that are provided in the Fast Track programme, which include pdf docs, videos, and lab exercises, are sufficient if your only goal is to pass the pre-assessment and live exams. However, if you really want to be able to work with this equipment and understand how JunOS works, then you need a lot of practice. Like Dynamips for IOS, Olive is the best choice if you don’t have access to real Juniper boxes. Although Dynamips and Olive are not officially allowed by Cisco’s and Juniper’s policies, respectively, it is common knowledge that a lot of people use them and are widely available. All you have to do is do a few searches in Google and you will find what you need (for example, here is a good guide for creating an Olive).
JNCIA-ER & JNCIA-EX
These exams are fairly easy and straight-forward, but keep in mind that Juniper certifications are very much vendor-oriented. You will normally not’t find as much questions about technology as you would in Cisco exams.
JNCIA-JUNOS
This is the first IT exam that I have failed. With a score of 81! Embarrassing, huh? :) The passing score is 85%, which is pretty high for an exam with 85 questions for 90 minutes! To be honest, I didn’t really study much for this exam (less than 3 hours) as I had already passed IA-ER/EX, which are valid prerequisites for JNCIS-SEC, and went just for fun :) Well, as it turned out this failure motivated me even more and although I was not really planning on taking the IS exams, this turn of events completely changed my mind.
JNCIS-SEC/ER
These exams might look difficult to some, but are not really such if you have studied hard. Be prepared to deal with lots of Juniper implementation specific stuff and play word games. I have to admit saying “This exam is an absolute joke” after taking the JNCIS-ER as there were some ridiculous questions that tested my memorization of command syntax rather than my knowledge.
At last, I can easily say that you are not going to acquire much knowledge about technology as these exams are pretty much vendor-oriented for the most part. But if you really want become familiar with Juniper equipment, these certifications are a good way to push yourself and explore JunOS.
My brother, Stefan, is looking for a full-time permanent or contract job in Asia or Europe, preferbly the UK. He has 7+ years of experience in the IT field, extensive knowledge in routing & switching, security, service provider solutions and is an unassociated CCIE Routing & Switching. Click here to take a look at his CV.
Now that I have finally completed my high school studies and boring and tedious stuff is out of the way, I am starting to make new plans for the upcoming months. I have already accepted an unconditional offer to study Telecommunications Engineering in the Glasgow Caledonian University and almost everything is set up there so it’s time to get back to my studies. I will probably take a few weeks’ break until I start again, but it’s very important to have a plan beforehand. In the meantime, I covered IPSec extensively as this was removed in the R&S track a few years ago and wanted to get the grip of it.
Paths
The paths that I have considered in the months between passing my CCIE R&S lab and now are very different and include:
Microsoft Certified IT Professional
Linux
CCIE Service Provider
The reason I chose to study Telecommunications Engineering over Computer Networks & Security or other similar courses was the chance to broaden my knowledge and have such in different areas. That is why I prefer a course with a wide area of knowledge to a very “tight” course. To be honest, end-user applications/OS do not really draw my attention so it’s not something that I feel like dealing with in the future. However, I realize that only by having knowledge in these areas in addition to networking can I succeed in the jobs market.
MCITP
This certification seems interesting as it consists of 7 exams, $50 each. I am not really pursuing certifications because being certified does not mean anything by itself, it just means you’ve passed an exam. The way that you gain it is what counts, but no-one could argue certifications are a great facilitation to get that knowledge by setting yourself a goal.
I took a look at some of the guides and to be honest the stuff inside is not really rocket science as most of the things are like which thing is situated where and what this option does. So I’ll leave that certification for my term-time, when I expect to have very tight schedule and very little time and Microsoft books would be much easier to read than ISIS or AToM :)
Linux
I’ve been advised by many of my friends to play around with Linux and try working with some of the services available like NAT, Firewall, DHCP, DNS, FTP & HTTP servers, etc. That I will probably leave until I finish my CCIE SP track.
CCIE SP
I think CCIE Service Provider should my next step. First off, I’d like stay in shape after my CCIE R&S lab so that my knowledge is fresh. Second, CCIE SP seems to be a natural and appropriate path after R&S as the similarities in the blueprint are most compared to other tracks. Besides, I’ve already read a few books about MPLS and it really got me interested. CCIE Security was another way to go, but I think I’d better leave it after SP. The only thing that I am thinking of changing in my preparation for the SP track is passing the written after I am done with all the books, RFCs, Configuration Guides, CoD and other video materials.
Yes!!! I did it. I nailed it on my first attempt on February 4th, 2009. I am now one of them.
Ever since I got into networking, I always wanted to be a CCIE and looked up to those guys. It was a dream and I realized it.
I took off from Sofia on February 3rd with the Hungarian Airlines. I had a connecting flight in Budapest as I was travelling with the Hungarian Airlines – Malev. I landed in Brussels and arrived at the hotel around 8.30 pm. My plan was not to study on the day before the exam. The only thing I read a few times that day was my plan for attacking the lab. What I usually do before exams is listen to some music and concentrate. During the two weeks before the lab, I slept like 5-6 hours a day because of jet lag from my trip to the US, lengthy sessions with live hardware, stress, and thinking what’s gonna be like if I pass or fail. When I arrived at the hotel – Holiday Inn Express, which is very close to the lab itself, it was about 23 hours without any sleep and all I wanted was to get some sleep and be fresh for the lab. In addition, my brother had given me a printed map with the CCIE lab location so I had nothing to worry. I ate a few Zingers and went straight to bed setting the alarms of two clocks :D Now when I think about it was probably good I hadn’t slept much in the week prior to the lab because I was completely knocked out in the evening before the lab and was able to sleep fine.
In the morning, I took a shower, dressed up, and had breakfast. It was 7 o’clock in the morning and the lab starts at 8 (gotta be there at 7.45) so I read once again my lab plan as I intended, and listened to some music. I was ready to go at 7.10, but as I already mentioned the hotel was very close, I’d been given a map, and it was very early to go.
7.20
I got my passport, phone, MP3 player, and chocolate and set off to the lab. It was dark and kinda cold. I got to the place marked on the map in about 10 minutes, but I was shocked – there was no CCIE lab building or any sign of the CCIE lab location. My brother had told me it was a different building than Cisco’s one so I ignored the Cisco buildings in the distance. I didn’t know what to do. There was nobody out on the streets. Luckily, I met a woman, but she had no idea where the CCIE lab could be. I found one or two more people, but they had no idea where it was. I was sure I was at the exact location marked on the map so I called my brother. He was of no help either. I had to be there at 7.45 in the lab and it was already 7.42. I was completely desperate, I thought “What a joke!”. I then decided to go to Cisco’s building and find someone who might know where the lab was. Fortunately, a guy (THANK YOU) told me it was Cisco’s second building on the back of that one. Anyway, I got there at 7.50 and thank god the proctor wasn’t there yet, otherwise I would’ve had to wait maybe an hour or so for the proctor to walk me in.
The Lab
I was very relieved of stress when we entered the lab, probably because of all the running like hell for 15 minutes :)
Cisco had just made changes to the written and lab of the R&S track and introduced open-ended questions so that was the first thing you have to do in the lab. I revised some very basic stuff the week before the lab as I thought I should’ve acquired enough knowledge by that time to cope with the questions. There was, of course, some tension because this update was introduced just three weeks before my lab and I didn’t know what to expect. I did okay with the questions and it was time for the real lab. I read the lab twice as that was my plan, drew a table of four columns – Task, Points, Y/N, Notes, copied the running configs in flash, opened the Doc CD for routers and switches and started slowly. I knew there was no reason to panic so I configured, verified, and if needed, troubleshot everything calmly. I was done with about 60-65% of the lab by lunchtime. Food was okay, there were some bizarre meals being offered, but I stuck to an ordinary hot dog, it was definitely not the time to experiment. During lunchtime, I built my strategy for attacking the rest of the lab. I was thinking of which tasks to complete next in order to get a pass mark.
I finished with the whole lab in exactly 5 hours so I had 3 full hours to verify and troubleshoot the whole lab. That was kind of boost and I decided to take a brisk break for refreshments. I managed to make two full verifications of the lab and although I found a few mistakes I’d made, I was sure I configured the tasks correctly. TCL scripts and macros are a great help and I highly recommend making use of in your preparation and in the real lab. I ran the scripts the whole day and that helped me a lot. I also asked the proctor a LOT of questions for things I considered vague and although he was a bit grumpy after my 10th question, I didn’t really care about it :) Anyway, I had 20 or 30 minutes left and nothing to do, but as Brian Dennis suggests “Never leave the lab early, drink as many free drinks as you can if you will, but never leave the lab early”. So I drank as many free drinks and ate as many fruit as I could. I was a bit paranoid at the end that I hadn’t answered all the open-ended questions in the morning, but after a bit of thinking I remembered all the questions and was very relieved.
Walking out of the lab, I thought I had a great chance of passing the lab. I met another Bulgarian, who was doing the SP track, and chit-chatted a little bit. Then it was time to drink a few beers as per my plan and relax. If you ever go to Brussels, drink Stella Artois. I don’t know if it was the beer or not, but that felt like the best beer I’ve ever drank :).
I woke up in the morning, had breakfast and went straight to the nearby hotel, where there is a free Wi-Fi, to check my results. My heart was beating like hell, and before I logged in to check my result, I said to myself “Even if I haven’t passed, I will be back and pass the second time”. I logged in and I saw:”Brussels CCIE Pass”. I didn’t believe it at first and thought I was looking at something else, but after reading going over it a few times, I was jumping in joy :D I felt as happy as I felt relieved I wouldn’t have to go through the same thing again, but also felt a bit sad that it was over.
I would like to thank these people for helping me out on my way to the CCIE certification:
My brother
My friends and family
Jun Kim
All Dynamips and Dynagen developers and contributors
It was 2005 and I knew nothing about networking and very little about computers. My brother urged me to enroll in a Cisco Networking Academy. A year later, I was officially certified as a CCNA.
Then I took a month or so off networking and was thinking of enrolling again in the netacad for CCNP. As you probably know, it’s expensive when it comes to CCNP so my brother told me to study at home from books. I had to choose between BSCI and BCMSN. I went for BCMSN (switching). It got very, very interesting. In the meantime, my brother got his CCNP and started his CCIE preparation. He realized that about 50-60% of the material in the CCIE R&S track was covered in CCNP so he advised me to start preparing directly for CCIE because it was not worth spending $600 for exams (now it’s even more) just to get a professional certification. As I see now professional certifications, they are just useful if you want to get a good job or a higher salary. But when you are 16, this is not the case. Yet, I was hesitating BIG TIME. It looked quite daunting to me and I was more inclined to go for the CCNP first. I decided then to post in GroupStudy and get some advice (more here). There were different opinions and only 2 or 3 of the people who posted advised me to go for the CCIE. Everyone else either said I’d fail, I couldn’t do it, it wasn’t worth it or I’d trade my childhood for money. Despite that I went for it.
The Journey Began
I started preparing for the written exam. Don’t get me wrong by saying I didn’t prepare for the CCNP certification. I still covered the material in the CCNP track, but I didn’t take the exams and there is just some extra stuff in the curriculum that I did not need to know. So I read BSCI (without IS-IS) and BCMSN end-to-end.
As I went through the material, I encountered an enormous amount of unfamiliar concepts. It is a real struggle until you get to the point where you have enough knowledge to bind concepts together and build the whole picture. I was lucky my brother answered a lot of my question because I really had a LOT. It was 2 or 3 months before they officially announced the changes to the written exam blueprint. They added MPLS, DMVPNs and some IPv6 advanced stuff. Go figure what MPLS and DMVPNs are for in this exam, but I had to learn them. So I copy/pasted the blueprint in a doc file and made a plan. I didn’t make a detailed plan, it was just “topics covered, topics in progress, topics to be revised”, some deadlines and “GOAL: CCIE Written Passed”. Meanwhile, I got into a traineeship in one of the several Cisco Gold Partners in Sofia. There I was assigned a task of preparing a lab for the Cisco Gold Partner Audit. There was MPLS with VPNs and Traffic Engineering. I had no idea what MPLS was then so I read 3 books for a little less than a month and had some devices where I was labbing all day long. MPLS was pretty interesting to me, but as soon as I realized I didn’t have work to do, I switched back to my CCIE preparation. I decided that I should put pressure on myself and schedule the written exam in order to get the topics covered in a more timely fashion. I passed the written exam in October, 2007, about 8-9 months since the start of my preparation. I don’t regret taking the written exam early because I considered it a step I had to make. I wasn’t kidding myself thinking that passing the written meant anything, but I wanted to get it out of my mind and not worry about technologies only covered in the written. By the time I got to this point, I had already read the following books:
Cisco Multicast Routing & Switching
CCNP Self-Study BCMSN Official Exam Certification Guide, 4th Edition
Cisco Press 2000 – CCIE Developing IP Multicast Networks (skipped some chapters)
Cisco Press 2000 – MPLS and VPN Architectures
Cisco Press 2001 – Routing TCP-IP Volume II (CCIE Professional Development)
Cisco Press 2002 – Traffic Engineering With MPLS (skipped some chapters)
Some of the books I read twice because when you don’t practice the theory intensively, you forget it easily. Of course, I made a lot of labs, but they were just to get things tested how they work and to explore cases not mentioned in books. Almost everything weird I could think of, I labbed it. That really helped me understand some of the core technologies like OSPF, BGP, EIGRP, MPLS, IPv6, Multicast, QoS, etc.
The Extra Factors
The CCIE is a really long and lonely journey. I experienced it myself. I didn’t expect anyone to learn the things or do the dirty work for me. I’ve really had a lot of ambition, and most importantly I had the time, dedication, and commitment. Of course, not having a girlfriend gave me a lot more time than I would’ve had it been the other way around.
So the aforementioned things helped me, no doubt. But there were also factors that a lot of people would be influenced by. I can’t tell you how many times I met people who tried either to discourage me, didn’t believe I could do it, just didn’t take me seriously, or even laughed at me. This can sometimes be quite daunting, but that wasn’t the case. I constantly heard people saying “You need experience to become a CCIE“, and ”without experience you’re just a paper CCIE“. That’s total crap and I don’t give a shit about it. The more I meet/met such people, the more determined I become to prove them wrong. In my opinion, it is very important not to care about these things.
After the Written
It was time to make a plan for the lab. I think making the plan for the lab was one of the hardest things because there is so much stuff that you rarely know where to find resources and what exactly you will need. The plan looked like this:
I copy/pasted both the official lab blueprint from Cisco’s website, and the one that InternetworkExpert provides. If it was a technology that I had to acquire more knowledge for, I read books and documents from Cisco’s website including config guides.
Topics were marked either:
In Progress
Covered
To be Revised
Not Covered/Partially Covered
Then I had “Books to Read:”
Regular Expressions – http://www.cisco.com/en/US/docs/ios/12_2/termserv/configuration/guide/tcfaapre.html (BGP only) & Cisco Press 2001 – Routing TCP-IP Volume II (CCIE Professional Development) (Appendix B only)
QoS – Cisco Press 2005 – Cisco QOS Exam Certification Guide IP Telephony Self Study 2nd Edition
Cisco Press 2001 – Routing TCP-IP Volume II (CCIE Professional Development) (MSDP only)
I read these end-to-end. You will probably say I’m insane and I probably am, but I wasn’t just reading these for the lab, I wanted to improve my IOS culture. It’s really an enormous amount of work and thousands of pages to read, but I found it really useful to read all of them. It took me like 6 months to read all this and it was a lot of tedious work sometimes. This is probably the time I acquired studying habits that I will also benefit from in the future.
I left the 3550 and 3560 configuration guides last because I wanted switching to be fresh in my mind when I was about to start labbing, and I also found myself not having access to switches except for those on the PEC, where you can only find a 3550 in a lab provided by NIL.
The boring stuff was over. Lots of theory in my head and lots of scenarios to lab. I’d decided that InternetworkExpert’s Class-on-Demand series should be the next step in my preparation. I watched some of the videos just before I took the written exam as I had some doubts about certain things in FR and Switching. I was highly impressed with the CoD. You get so much knowledge in so little time and it’s a pleasure to study this way. So I watched all the videos, that is two weeks (10 days) worth of training with about 5-7 hours a day. I highly recommend the CoD, it’s probably one of the best, if not the best training you can get for the CCIE.
Then it was time for labbing. I quit my job because I needed more time and wanted to completely concentrate on my CCIE lab preparation. I used to teach CCNA classes as Joseph Brunner suggested in a topic in GroupStudy, but it wasn’t fun anymore, and probably because I could hardly ever gain free access to 2960s from then on, which was the reason I agreed to teach classes in the first place.
I started with InternetworkExpert’s volume 1 workbook, which includes plentiful of labs on all topics from the blueprint. These are very useful as you get to test many features you’ve only read about, and also because you get to configure all possible scenarios of a technology working alone and not interfering with other technologies.
After that I moved on to IE’s workbook volume II. At first, I found it hard to interpret the wording of the tasks. Speed was another issue, but I always tried to configure and think about all tasks. Later on, when I was a month or so before my real lab exam, I started worrying about speed and tried getting 80 points in 8 hours, but as I did more and more labs, my speed improved with every session. By the way, do not do the Dynamips workbook labs if you are using Dynamips for your preparation. Do the regular labs and just write the solutions you cannot configure in a notepad and then check your solution with the solutions guide.
So I did 10 labs from IE, then I moved to IPExpert’s v9 workbook. I didn’t do the first 18 labs or so because I didn’t have much time and they are practically the same as volume 1 workbook of IE so I did the first 10 multiprotocol labs. When I moved to IPExpert, I found out that tasks there were much easier, a little bit vaguer, but you have more freedom and most of the labs do not have initial configurations so you build the network from scratch. Then I returned to the last 10 labs of IE and then again to the rest of the IPExpert labs. The reason I switched between vendors so often was that I easily get used to the physical topology and I really wanted to be able to do a lab with any possible physical topology.
I am very thankful to a person from the local Cisco office who booked ASET labs for me. These labs are provided by LabGear, but are booked via Cisco and are only available for Cisco Partners. Contact your local Channel SE if you are interested. You have 6 built-in labs there and auto verification available to run. I also had 3 labs for this topology from a workshop in the local Cisco office my brother attended plus the CCIE Practice Labs. So it was 11 labs that I did in 7 sessions. I had 8 sessions booked – 4 in the beginning of January, just before I took off to San Jose, and 4 a week before the real lab. So in the last session I labbed all the Catalyst features I could think of. I wanted to know how to configure them in case I get them in the lab. The list is as follows:
Local Proxy ARP
Flex Links
MVR
MST
3550 QoS
3560 QoS
IP Source Guard
DHCP Snooping
IGMP Snooping
L2PT
QnQ Tunneling
Private VLANs
RSPAN
Protected Ports
Port Blocking
SDM Templates
Voice VLANs
UDLD
Fallback Bridging
Smartport Macros
802.1X
HSRP with Port Security
Flow Control
3560 IGMP Profile (available on 3550 as well)
IGMP Max Groups
Loop/Root/BPDU Guard and BPDU Filter
Etherchannel
LinkState Tracking
Jumbo Frames and Routing MTU
System MTU Change
VLANMAPs/ACLs
Error Disable & Recovery
IGMP Snooping
MLD Snooping
I also watched once again Netmasterclass’ VoD for Catalyst QoS as this is a very vague topic and to be honest I still have some things to clear up. The video is amazing! It explains a lot of things about the 3550 and 3560 QoS so I definitely recommend watching it. Not to mention the amazing posts in some of the blogs out there on the Internet. Remember this: Google is always your best friend. I’ve found so many things in blogs, IE and IPExpert forums, and of course GroupStudy, which I couldn’t find in any book.
So it was February 3rd and time to take off to Brussels. I will post about the actual lab in a separate post very soon.
Last year CsillaBessenyei (Hungary), Christian Sandescu (Romania), GregaPresenen (Slovenia), Boris Dekovic (Croatia), and I won prizes in the Netriders Challenge, which was the first organised for whole Europe. 24 countries took part in it and not surprisingly to me the winners were all from Eastern and Central Europe. It was 50-50 whether I was to be allowed to participate as I had to be 18 to fly to the USA, but luckily the trip was in January, 2009, which meant I am good to go. The challenge consisted of 3 parts – a theoretical test, packet tracer challenge, and a TAC call. To be honest, I am not the biggest fan of Packet Tracer and I have never used it in any of my studies, but I navigated pretty well in the competition. The fun part of the competition was the TAC call, where you had to act as a TAC and an engineer from Cisco would call you, pretending to be a customer and have a problem with its router, and you had to guide him on the phone. Pretty funny as I was not told in advance that I had to be on the TAC side of the call and it was really weird at first :)
On January 11th, I headed to San Francisco with a flight from Sofia. I had never travelled with a plane until then and it was kind of exciting. The flight to Munich was just a few hours and I had an hour and a half stay there to catch my flight to San Francisco. It was a long and exhausting 12-hour flight as we flew all the way over Iceland, Greenland, New York state and down to California. I have to say I was completely satisfied with Lufthansa, very professional work by the crew. If it wasn’t them to feed and entertain us all the time, it would’ve been a very boring flight. Unfortunately, I had no MP3 player as my Zen Vision:M broke a couple months ago and had to listen to Lufthansa’s radio or TV shows.
Anyway, I did not really know what we are going to do there as we received no agenda for our stay so not knowing what it would be made me look forward to it even more.
When I went through the exit gate, a taxi guy was waiting for me outside with a piece of paper “Pavel Stefanov – Netriders”. When we got to the car, I was completely astonished. It was a very nice and spacious Lincoln with leather seats inside. That’s not a bad start, isn’t it? Commuting to the hotel, I didn’t really know where I was. At one point I decided to ask the driver and he said “We are in Santa Clara”. So it’s a big mega polis there including San Francisco, Santa Clara, and San Jose and you don’t really know where you are until you see a sign.
I arrived late at the hotel – about 9 pm, and couldn’t make it for dinner with the rest of the guys so I had to meet them on breakfast in the morning. We stayed at Hilton Garden Inn, which is a really nice hotel, and I will definitely stay there if I come back to San Jose some day. The beds were king-size, with 5 pillows, and as I told the guys “sleeping in those beds for 9 hours feels like sleeping for a whole week”. There was also cable Internet (and FREE unlike hotels in Europe) and I was so happy :)
Day 1
In the morning, I met the rest of the winners and Penny Bradley, which made all this competition and trip possible. We were taken to building 5, where we introduced ourselves, met Amy Christen, the vice president of the Networking Academy programme, and then were given a brief presentation about Cisco Culture by Isaac Majerowicz. We were very hungry by that time and went to Cisco’s cafeteria. It is a very big hall with all kinds of food – Chinese, Indian, European, American, basically anything you can think of. There was also a Cisco burger which I had no other choice but to taste the next day, tastes pretty good :) And I had never seen so many engineers at one place, let alone Cisco employees, will never forget that landscape :). My eyes were immediately on the Cisco Merchandise Shop, where I bought stuff for $100 the next day :). Cable Lab with Joe O’Donnel was next on the list. I can tell you one thing – this guy is a guru. He used to be a mountaineer in the past, but like Jeff Doyle, who gave up a career of psychiatrist to become one of the most respected engineers in the field, he decided to go with networking. Joe is currently something like a manager of the lab, a lab in which Cisco has invested at least 200-300 millions of dollars in recent years.
In this room, there are devices downloading channel streams from satellites, those streams are demultiplexed, then encapsulated into IP headers and finally multicasted inside Cisco’s internal network. They use a different device for every one of these processes so what’s that virtualization Cisco is constantly talking about on conferences? :) Anyway, these channels are only used by Cisco employees and Joe makes sure everything works smoothly so that he doesn’t get called by John :) Then we entered the *real* room. We weren’t allowed to take pictures there for obvious reasons, but I can tell you one thing – it felt like heaven – more than 15,000 cable modems making noise and enormous ventilation systems beneath the floor cooling the whole room. Interesting fact – when they moved to the building, it was just a regular room and they had to turn it into what it is now, but not just do the whole moving, they had to do what they did for 6-9 months in the previous building in just 3 days. Can you believe it? They did the whole thing, 15,000 modems, cabling, cooling, content delivery systems, everything. No wonder why Joe feels pretty proud of this accomplishment. Then you would ask, what does Cisco use those modems for? It turns out that whenever there is a new Cisco IOS release, it goes through an enormous amount of testing, and not just testing of new features, they test the new release if it is compatible with every single Cisco IOS release there’s ever been. I was amazed, and still couldn’t explain why I find bugs in the IOS occasionally. The answer was simple “We can’t test every possible scenario, and if even if we could, it is not worth doing it” (or maybe it was “it wasn’t cost-effective”, not sure). Fair enough. They also had some kind of environmental change machine that they use whenever Cisco receives hardware that is suspected to have faults.
Executive Briefing Centre was next. This is where Cisco brings customers when they want to be shown some technology working. It is a beautiful building and the area where we were presented the latest Voice solutions looked more like a disco club :)
I was pretty overwhelmed by the end of the day and really happy with my experience during the day. We decided with the rest of the guys that we were very tired so we went straight to Applebee’s, which is only a few meters from the hotel. I was very hungry and didn’t have a clue how big portions are in US restaurants so I ordered a Santa Fe salad with a chop steak and fries. The guys had a good laugh while I was struggling to finish my dinner.
Day 2
New day, more energy, no jet lag. Speaking of jet lag, my body clock fits perfectly into the Pacific time zone as I used to stay up until 7 am doing labs at home. We had a job shadowing session planned in the morning. We had to choose between Ali Moghadam, a software developer at Cisco, or Dennis Frezo, who is dealing with the development of Packet Tracer. So considering the fact, as I mentioned earlier, that I am not really into this application, I went for the session with Ali. I think this was one of the most productive things we did there. Ali is a very down-to-earth man and was happy to share with us a lot of things. I completely changed my vision of how an employer should treat an employee and how a simple working day should look like. Something I forgot to mention earlier is that when we went into the building at 9 am, there was not a single person in most of the halls (where everyone has its own cubicle). So Ali explained that in Cisco it doesn’t matter when you go to work, when you leave work, or where you do your job. It’s all up to you. You can work at 4 am in the morning in the office, you can work every day at home through a VPN (by the way, every Cisco employee gets a free 800 series router, cool, huh?), it doesn’t matter. All you have to do is keep up with deadlines and do your job. It was also interesting to hear how he got his job and how he got into software engineering. I confessed I knew very little in this area (I still do) and was wondering where he got all this knowledge from. The answer was very relieving – from university! About the interview – it was really fun as he told us he had two interviews, one with Cisco, and one with another company on the same day. He had the interview with the other company first, which went really well, they even sent him the contract immediately by email so he didn’t really try to put much effort into the second interview – a 4-hour interview with plentiful of technical questions. I was surprised to hear that there had been no HRs during the interview and no stupid “How do you see yourself in the future? What are your plans? Describe yourself. What’s your biggest weakness?” type of questions that when you hear on a regular interview, you just want to slay the guy :)
The afternoon was designated to visiting Stanford University. I would lie if I didn’t say I’ve never stopped dreaming of studying there since Jun Kim told me of it. Stanford University is saidto be one of the most prestigious universities in the whole world. Classes are very small, tuition fees are very big, and places are very few.
This is an example of taking a class in the beautiful gardens in the campus, speaking of which it is enormous and includes very big territory. It has its own two hospitals, a church, stadiums, etc. The library is impressive, consisting of more than 2,500,000 books and you can practically find any book you want.
Technology – it was everywhere. The university has spent tens of millions of dollars on the most innovative technology. But it’s not just a lot of technology at one place, you see technology integrated and working hand-in-hand with education. Classrooms are state-of-the-art and the university actually has started taking another approach to designing classrooms. As opposed to the regular classrooms where the teacher has its own desk and students sit in front of him on their desks with a white board behind the teacher, the classrooms in Stanford are very spacious, opened and look more like a cafe than a real classroom. They have found that this new approach boosts students’ effectiveness and helps them relieve stress.
The university is where people like William Hewlett and David Packard graduated or children of presidents from the whole world study.
Dinner was at the Campus Cafe and I ate lobster ravioli. They were pretty delicious although it looked more like a soup than a meal.
Day 3
On day 3, we were joined by Bob Schoenherr, organizer of world competitions and network consultant at Cisco. He was born in California and everybody loved him right away. Even at the end of the trip some of us said that Bob was the best part of the trip :)
In the morning, we had a Telepresence session booked in one of the Cisco buildings with friends of Csilla, who were in Hungary. I was very impressed with this technology that I was exposed to for the first time. It is basically three big flat screens, each consuming about 5 megabits of traffic, HDTV cameras, and of course point-to-point links between the places. Telepresence sessions are very expensive because they consume a lot of bandwidth and require very good QoS characteristics. In addition, every Telepresence room must be built in accordance to the same design so that you really get the feeling you are in one room. All that is different in the rooms is the sign on the wall with the city’s name. I really felt we were in the same room. I was even told a funny story where a guy inadvertently dropped his bottle of water and another person from the other end of the session tried to catch it :)
The rest of day was for San Francisco. What can I say? I fell in love with the city. It’s a unique and charming city. San Fran is built on 29 hills and that’s the reason roads there are extremely steep. First station was the seaside from where we took pictures of Alcatraz. We didn’t have much time so we couldn’t visit the prison. A beautiful view from the Golden Gate Bridge was in front of us. Bob pointed out that the bridge is named after Golden Gate (which is just a narrow part of the ocean), not that the place got his name from the bridge.
I felt so small. Apparently, during the World Wars, the Americans laid submarine nets in the ocean to protect from torpedoes and Japanese submarines. It was a quite peaceful place at that time and the city accepted a lot of immigrants from Chine during the Gold Rush, but it turned out there is not much gold in the valley. This is why you can see a lot of Chinese or predecessors of Chinese people there.
At lunch, we went to the wharfs, where we had white chowders. It’s basically a small loaf with a hole in it where the soup is. I recommend eating this if you have the chance to go there. From there we headed to the downtown of San Francisco by cable cars!!! I think this is when we really got the feeling of the city. This area is really beautiful, with a lot of modern architecture and high buildings. Another thing that stuck in my mind was that I could see a real community – from the homeless beggars on every corner to the well-dressed businessman carrying his brief case probably with contacts for millions of dollars.
Chine Town was next – a great chance to walk around this area. I truly felt like being in a Chinese city, but we didn’t stop there for much longer. Bob had mentioned earlier Fry – the biggest electronic store in the world, and Christian and I were eager to go there. He wanted to buy the Creative X-Fi PCMCIA sound card and I wanted to buy the player I could only dream of buying in Bulgaria – Creative Zen X-Fi. The store was gigantic. They sell every single electronic thing available on the market there. It was like heaven for geeks :)
Dinner was at an Indonesian restaurant, food was okay, service was great, drank some very good Singaporean beer.
Day 4
I felt really sad in the morning that we were leaving on Friday. But then I thought “Hey, I have another week in Atlanta”.
Thursday was for Apple’s Headquarters. Cisco and Apple have established a partnership not so long ago and the first fruit from this partnership is WebEx being available on the iPhones. We met Wendy Walker, the Sr. Marketing Manager of the company, and were given a short presentation on what the company has been doing since its establishment, how it progressed to being one of the leaders in multimedia solutions nowadays, and the range of its products. I am not going to lie to you and say this is my favourite company as I am firm admirer of Creative and as I already mentioned I just bought the Creative Zen X-Fi. So my already existing impressions were confirmed – Apple is a very proprietary-oriented company and focuses exclusively on end users. Maybe this is one of the reasons for their success, but sooner or later they will have to open up a little bit and partnering Cisco is maybe one of their first steps. On the other hand, the company idolizes the word “innovative” and I was really impressed with their vision and the fact that they really adhere to it. Their products are madeto be very user-friendly, easy-to-use, and last but not least beautiful.
I learned a new, awesome term- BSAs (bandwidth-sucking applications) :D WebEx is probably one of them.
We had a lunch at Apple’s cafeteria and they boasted they stole Google’s Head Chef :D
The last interesting thing for this day was the Compliance Lab with TonnyYoussef. This is where any product that you’ve seen available on the market from Cisco has passed before being announced and where products reach end-of-life before they are even produced :). Here, devices are tested for safety and assurance. Most companies prefer to outsource this kind of work, but Cisco has decided to do this itself. Few advantages – smaller amounts of time for testing, as a result they can create a new product before their competitors, smaller chances of confidential information being leaked out, from what I heard Cisco employees are very loyal. Anyhow, I was astonished to see what hardware is tested against – low temperatures, very high temperatures, earthquakes – 8.1 on Richter Scale, RF and sound emission, high pressure, ability to be used by disadvantaged people, compatibility with other vendors, possibility to stick your finger into the device and get electrocuted, ability of the device to inflame. Amazing, isn’t it? And they video tape most of these procedures and send them to some of their biggest clients like AT&T, Verizon, etc. Cisco is just one of 4-5 companies in the world that does this kind of stuff. So from now on, whenever you’re mad, Cisco hardware is an option… :)
We also got to see Cisco’s data centre, which looked very decent, but Bob told us the one Cisco has in Texas is really one of the greatest and an example of Green IT.
Day 5
Csilla, Boris, and I had to give short presentations to 10-15 people from Cisco about our trip and how it impacted our careers whereas Christian and Grega talked about career opportunities in the IT. Grega and I left earlier because I had to catch a flight to Atlanta so we said good bye and that was it.
This week was one of the best, probably the best, in my life and I will never forget it. I liked a lot of things about the USA and was proven wrong to have any prejudices. I will never ever have such, I’m sure about that. People in the USA are very friendly and are smiling all the time. It took me awhile to get used to it, but I loved it. I met so many new and different people from all parts of the world and I noticed no discrimination at any time. One thing I was unable to get used to was that everything was big – buildings, sings, streets, advertisements, food portions, cars.
I felt kind of sad at the end, but I know some day I will meet these people again and will be back in San Jose and San Francisco, cities I fell in love with.

I’ve had difficulties with some task in the Internetwork Expert and IPExpert workbooks asking to configure the router to supply the address of a CallManager server to hosts so I decided to show you where you can find the numbers of the DHCP options in case you forget them during your lab.
Supplying the CallManager address can be done via two DHCP options, that is option 66 and option 150. Both options actually specify a TFTP server address (option 66 can also specify a FQDN (fully-qualified domain name), but the IP Phone would need a DNS server to resolve the name to an IP address). Cisco recommends using option 150 because option 66 might be used for some other purposes in your network.
Now, to get back to the purpose of this post – locating those two options on the Documentation CD:
Go to www.cisco.com
The Support drop-down menu and then under Maintain and Operate
Voice and Unified Communications -> Call Control -> Cisco Unified Communications Manager (CallManager) -> Maintain and Operate Guides
Choose one of the Administration Guides and under DHCP Server Configuration you should be able to locate the numbers of the DHCP options (Note: If you choose a 6.x or later Administration Guide, the DHCP Server Configuration is located under System Configuration)
HRs must be the smartest people on Earth having developed so many new technologies or introduced new terms in networking :) Don’t you just love it when they put some words together they’ve googled or got from the first networking forum?
“My Dublin based client is seeking CCNP or CCIE or CCVP Network Engineer to work in a Network Design function – You will be working within their Data Centre & MPLS wireless network.”
Тази година Сиско Експо ще се проведе на 28 и 29-ти октомври, както през миналата година в кино Арена Младост. Цената за вход е 48 лв. с ДДС. Регистрация можете да си направите в сайта на Сиско България – www.cisco.bg до 27-ми октомври. На пръв поглед се отличават някои по-интересни презентации в програмата на експото, сред които тази за Catalyst 6500, DWDM, Service Control Engine, CallManager 7-ца и 6500 VSS.

I believe it is very essential for anyone pursuing a career in IT to be always able of taking a step forward when he sees others are trying to push him backwards. So just before I started my last year in High School I decided to make that one little step that I hope will probably prove to beof great importance.
I made the decision of quitting my job. A year or two ago while, I posted a topic in GroupStudy on whether I should go first for CCNP and then for CCIE or just directly give it a shot. I received a great support from some of the people most active on the threads then like Joseph Brunner and Jun Kim, which told me to go for it. I remember Joseph Brunner once posting a topic that teaching a CCNA course or any such Cisco courses would be of great help to your future career. That is one of the main reasons I joined my previous company where I was dealing with CCNA trainings in the Networking Academy at my High School of Mathematics. And now after looking back at those 9 months of my career, I squared accounts.
Teaching a course in networking even at my age of 17 was a great experience. I improved my presentation skills as well as my teaching and explanatory skills, but also remembered some of those essential but easily forgettable details. I build the rack, I build the Networking Academy network and infrastructure, I build RA VPNs, and I loved being the one building it! I met new people, some of them are already my friends and are also seeing their future in the networking field. What else did I got? Despite the financial reward was not to be the best, I can only be happy that I had access to Cisco boxes. Although I use Dynamips for my current CCIE preparation, there were 6 2960 switches in addition to the 1845 routers. I used them to test lots of catalyst features, although many lack in comparison with the 3550s and 3560s. I attained CCAI certification which is just something extra, but one of the great benefits were the free Cisco vouchers, for which I wrote in a previous topic. In addition, when I first joined the company, I was sponsored for the Cisco Express Foundation Specialization. So when I look back at my time in the company, I can pull out a lot of positives from it!
However, it was time to let go. I needed more time, more freedom and more space. So now was the problem with the hardware that I used for running the IE topology using Dynamips. Before that, I used the Networking Academy’s PC’s through an IPSec VPN and the topology was running on 4 PCs with 1 gig of RAM and about 1.7-1.8 Ghz processors. So I knew I needed something powerful and although I did not meet much support on the forums for hardware recommendations, I bought a rather powerful desktop machine with 4 Gigs of RAM, Intel Core 2 Duo 2.66 GHz and a Gigabyte motherboard. With all the other peripherals, that thing cost me 700 levs, which is approximately 350-360 euros. Not bad, huh? Well, I didn’t buy a monitor because I have my laptop and use Remote Desktop.
How is Dynamips performing? Well, if you use Windows and 3725s, you’re gonna have some problems. With Linux distributions, everything worked perfect and pings traversing 10 routers running with all tasks completed had a very low value – 100-200 ms. Unfortunately, I am a bit lame with Linux and decided to use the good old Windows XP. Running the full lab with 3725s can bequite an issue. This is also because with Windows and 32-bit systems only 3 gigs of RAM are available and 2 gigs per process at maximum. Now I am back with the 3640s and although they are not as stable as the 3725s, I cannot bitch about it, everything works fine. I could also have the second Dynamips process running on the laptop, which has 2 Gigs of RAM and Intel Core Duo processor at 2.16 Ghz, but I encountered some issues with the NAT being done on the Desktop machine, which I haven’t resolved yet.
So that’s pretty much what I consider a good step in my career and an important one to my CCIE preparation. I’ve already booked my date for the lab and now have the time ticking. Time will go very fast and I know that so I try to remain 100 % focused on it. I’m now on Lab 5 of IE’s volume II workbook and I really enjoy labbing. Time for completions is not that important at this point of my preparation so I am just trying to complete all of the tasks. Many of my problems are with the wording of the questions, but I expect to get better at interpreting questions as I go through the rest of the workbook and the IPExpert one as well.
So this much time I had to waste ;) Now back to my studies…
Today is the day I certified as a CCNP. Do I feel happy? I wouldn’t say so. When I received my last score report and the VUE admin congratulated me on becoming a CCNP, I just politely said “Thanks”. You have already probably guessed why I don’t feel certifying as CCNP is something I am excited about. It’s simply because of the quality of the exams. First, as a side note, Cisco is making a big commitment to its Networking Academy instructors by offering any instructor who has taught at least 2 classes in the last 12 months free vouchers for all CCNA and CCNP exams with 100% discount! So when I got the news last week, I scheduled my exams for this week.
On Monday, I took the BSCI. It’s a pretty straight-forward exam and there is not many traps you can fall in. However, I encountered a few questions that either had false answers (but were considered the right ones) or there was some silly wording in it. I cannot understand why Cisco would ever use silly wording in its written exams. I can see the CCIE lab being a place where wording has probably have its place, but why would you use vague wordings of the question in a CCNP exam? If you’re not a native speaker or are not used to those types of traps Cisco lays in, you will have your hands on your head wondering what is going on. This is not a testing of understanding the technology, it’s a testing of being able to interpret their questions.
The BCMSN was a rather good exam and although it was easier than BSCI, it tested your understanding in some cases to a deeper level. I enjoyed it and although there were again questions with no right answers or no wrong ones, it might show your theoretical understanding of technologies.
On both exams, I used the comment option and even provided them with steps to verify their answers, however, I do not expect my comments to be taken into account.
Although I cannot give any details about the other two exams as I do not want to break the Cisco NDA, I can just say be prepared for testing of skills that no good network engineer would ever use. There are some ridiculous questions on the exam that can put at least a big smile on your face. That being said, practice in the ONT and ISCW is essential to passing those two exams so take your time practicing with Cisco hardware and applications.
So why am I a person not appreciating this certification as an achievement? Well, this exams among many other Cisco ones have been devalued by a load of brain dumpers who make this exam less and less valued in the IT.
I almost fully agree with what Greg Ferro has written on his website regarding the possessing of professional level certifications. And although there are many in the CCIE world out there who will say the same thing about the CCIE programme and have even let their CCIE certifications expire, I still think that being a CCIE is something that is worth going for!
Това може би е новината на месеца в networking-а – едно от най-известните CCIE-та преминава към безспорния конкурент на IE – IP Expert. Досега Scott беше vice-president на IP Expert, а сега става част от екипа на може би най-позлвания в момента vendor за CCIE Training & Workbooks. Няма съмнение, че тва е огромна новина за IE, тъй като много от хората до този момент се доверяваха на IP Expert може би основно заради репутацията на Scott – ето и Resume-то на Scott, което наистина е доста внушително. Вижте само как изглежда личният му лаб – http://smorris.uber-geek.net/lab.htm. Не крия, че той е един от хората, на които се възхищавам много и заради които си прекарвам времето основно с networking.
Аз лично ще ползвам както IE, така и IP Expert, но изглежда сега, че IE ще станат най-вероятно абсолютния лидер на пазара.
Phew, мога да си отдъхна засега -http://cciepursuit.wordpress.com/2008/06/23/internetwork-expert-no-rs-ccie-changes-announced-at-networkers-so-far/. Миналата година стана много неприятно, защото изпуснах срока със доста малко, когато смениха blueprint-а за written-а, наложи се да изчета куп нови работи, които ги няма на лаба, и въпреки че не бяха в никакъв случай излишни, не искам това да се повтаря особено за лаба. Стискам палци да няма повече новини от Networkers. Единствената промяна, както пишат в блога на Internetwork Expert, Brian-ите, е че може Frame Relay-ът да се ревизира и да се опрости в някаква степен, макар че не мога да се представя колко повече може да се опрости, като се има предвид, че не представлява чак толкова голяма част от лаба в момента.
Въпреки че в почти всички тракове настъпват промени в blueprint-а или през тази, или от началото на следващата година и дори се заговори за CCIE Wireless track, R&S най-вероятно ще остане непокътнат поне до януари-февруари (надявам се) 2009, когато мисля най-късно да ходя на лаб. Fingers crossed!!!
Jeff Doyle е написал една много интересна новина в своя блог – очевидно ЕС се страхува да не се стигне до икономическа криза с изчерпването на IPv4 адресното пространство. На мен лично ми се струва прекалено налудничево твърдението, че в близко време ще се изчерпят всички IPv4 адреси, но въпреки това се радвам, че все по-често започват да се правят кампании за постепенния deployment на IPv6, защото предимствата са наистина огромни – те не са само в големината и практически неизчерпамото адресно пространство от 128-битови адреси, но и редица други, които ще дадат възможност на интегриране на нови услуги и приложение, които е или много трудно, или технически невъзможно да се осъществят с IPv4. Миграцията от IPv4 към IPv6 не изглежда изобщо трудно да се направи. Причините за неосъществяването на това се крие във все още недовършени стандарти (макар и малко), липсата на необходимост от ползването на IPv6 (крайния потребител не може да осъзнае сам какви са възможностите на новата версия IP, докато не го види с очите си). Въпреки това повечето мрежови устройства, операционни системи и сравнително немалка част апликации са IPv6-capable, така че разходите за миграция не биха били толкова големи, колкото до преди няколко години.

CCIE #20713 – на 6-ти май брат ми взе CCIE Routing & Switching още от първия си опит. Не мога да опиша колко се кефя, че го взе, на пук на всичките му тъпи български работодатели, на пук на всякакви статистики. Може би се кефя повече дори и от него :) Determination и dedication – скъса се от лабене, четене, лабене и пак лабене. Сигурно е прочел тонове документация, книги, рфц-та и т.н. Направи тонове лабове на Internetwork Expert и IP Expert, гледа CoD на IE, IP Expert и Netmaster Class. Преди можех да го хвана някъде на къс пас тук-там, ама сега за каквото и да гу бутна, е желязо. Не ме интересува какво казват доста от хората, които като срещна и разберат, че се готвя за CCIE, казват, че това CCIE да си нищо не значело, имало много fake CCIE-та, дето един NAT не могат да troubleshoot-нат. Нека си има, но заради този изпит научаваш технологиите inside out.
През цялото време бях сигурен, че ще го вземе, защото просто стратегията му беше правилна и единственото, което можеше да го прецака е wording и спичане (не съм го питал спичал ли се е, но изглежаше доста спокоен преди лаба, за сметка на това пък аз си чеквах icq-то през 10 секунди да видя има ли новини и резултати :) Сега е време да се полее успеха. В същото време обаче това ми дава и малко успокоение, че съм на прав път, защото вървя плътно зад него, но пък от друга страна и малко напрежение, че трябва да го взема от пърия път, защото иначе ще ми счупи крак :)
