Congrats to Drikus Brits, CCIE #34275

February 2, 2012

Almost two years after I passed my first CCIE,  an old colleague passed his CCIE with the numbers having increased by just over a 1000. Drikus then was part of our Mobility team, before he moved on to chase the big IE too.  It is really good to see that new fathers are tackling the CCIE and showing other it can be done. Despite the amount that passed since I sat down at the Cisco mobile lab,  Drikus earned his number after month of hard work.

A huge congratulations are most definitely still in order!

Drikus was kind enough to share the following:

“About a week ago I went for my CCIE exam in the hopes of getting my unique number. I passed the lab and became the proud owner of CCIE # 34275. A lot of studying went into this exam, and would like to thank beautiful and understanding wife & 2 kids. They provided me with the time and motivation to push through and getting it done, and a huge thanks goes to the Almighty up above. Secondly, a huge thanks to Ruhann’s RB Handbook. I purchased them back in the day when the short-notes just started out, and it has proved invaluable time after time again. The following should sum it up :

INE Routing and Switching  = $400
ipexpert Routing and Switching  = $400
Other available Courses  = $300
Ruhann’s R&S Handbook = Priceless”

Congrats to Jarrod Daniel, CCIE #30080

September 26, 2011

So we all knew this day will come, when the CCIE numbers would breach 30000. And this happened two weeks ago already. But the importance for those passing is not the region of the number, but the fact that hard work for them paid of as it did for the many before them.

One such individual is a fellow colleague of mine. Jarrod has been truly determined in obtaining his number. This is what he had to say:

“About week back I managed to conquer the lab exam and achieve number #30080. I am grateful to the almighty lord for providing me with the strength to push on through the past 2 years. I’ve come to learn that the number is just a reward and it’s the journey to obtaining that number which reminds me of what it means to earn a CCIE. I also realized that the journey never ends, obtaining the number is just the start. I am now equipped with sufficient knowledge to branch out into understanding and troubleshooting larger networks.

Having a strong support structure from family and friends plays a massive role in achieving this cert and you definitely played a major role in this space. I’ve had the privilege of working with you and having immediate access to a knowledgeable individual like yourself is a benefit on its own. Thanks to you Ruhann, for your guidance and your book which brought everything together the last 2-3 days before the exam. As always, concise and straight to the point.

Your dedication and contribution to the CCIE world is invaluable and much appreciated. Really looking forward to the SPv3 edition of your book.”

Congrats to Frank Hoban, CCIE #29701

August 6, 2011

The CCIE numbers are closer than ever before to 30000. When and to who will the 30000th number be issued? Would it be in two or three weeks time? Its becoming a rather interesting space to space to watch. It’s definitely a good time to be doing your first CCIE.

On that trend Frank Hoban from Ireland, contributed to the increase be earning his esteemed number the week before last. As to any before him, well done mate !

Frank is another candidate that somehow managed to find value in the RB handbook. :) Perhaps with the next big update around the corner many more might agree with his feedback.

“I got my CCIE Number last week. During my studies I used your notes constantly and always had them open for doing quick recaps on various topics. You clearly went to great lengths to create them and you are helping a lot of people. Keep up the great work !”

Thank you Frank for the kind words and good luck to your future family and networking endeavors. (In that order)!

Congrats this time to Nicolas Michel, CCIE #29410

July 5, 2011

Nicolas from France passed his CCIE R&S last week and earned himself the elite Cisco number awarded for months of dedicated hard work. His number is 29410, and it would seem at this rate by the end of July, perhaps middle August the CCIE numbers will reach 30000.

Nicolas an avid blogger at initialdraft.com wrote his CCIE story there. Nicolas shared some kind words about the RB Handbook he used.

“The book is simply amazing. When I was doing some workbooks I was also reading the notes I printed and I carried them EVERYWHERE !!! There are so useful. You will always forget something and the notes will always be there when you need to remember the information. At the end, the notes will be burned into your head and I can now tell you every examples that Ruhann wrote in his notes. I was not sure about some of them so I labbed them and now I’m pretty confident with what I learn :) This products is definitely A MUST HAVE !”

Now that Nicolas have passed, he can enjoy his wedding and honeymoon coming up, without taking his CCIE books with on honeymoon :D

As it all before him, huge congratulations!!!

Congrats to Michael Nabutali, CCIE #28640

April 19, 2011

I have not had much time lately, but I can certainly make time for some this. Micheal’s story is truly inspiring.

Michael Nabutali from Zambia passed his CCIE R&S last week. That makes Michael as far I know the FIRST and ONLY in his country to get a CCIE. That is remarkable. Michael contacted me for the first time in October last year after I passed my SP and he expressed his ambition to be the first CCIE in his country. He asked me for some guidance after his earlier attempts and I provided some basic info to assist where I could.

Also it is also important to understand, that Zambia being a third world African country does not have all the facilities as readily available as most other countries, so studying for a CCIE in some circumstances make it that much harder. But that did not lead Michael astray.  He was determined to pass and he did.

The biggest congratulations to Michael on his well deserved number and the pride of claiming the title in his country.

Michael had the following feedback:

“Hi Ruhann,

Thanks for the awesome routing bits handbook you authored. With God’s help, I passed my R/S lab in Dubai on April 13, 2011. Once I started doing full scale labs, I quickly realised I needed a book that would help me to quickly revise and understand the technology extensively. The routing bits handbook was my answer on this quest. Its compact but very detailed hence it was a vital tool on my path to become a CCIE.

The CCIE R/S booklist on the routing bits website was very crucial for me also. I did not know that the best QoS book was actually a professional level book by Wendel Odom. This was a major turning point for me because QoS was the greatest challenge I faced.

Thanks Ruhann for the excellent handbook and the awesome routing bits site posts. I strongly recommend the handbook for anyone who wants to pursue the CCIE for R/S.

Michael Nabutali, CCIE 28640″

Congrats to Robert Kosyluk, CCIE #28368

March 18, 2011

Congratulation to Robert passing his CCIE last week. Like many he is currently experiencing the great relief, accomplishment and happiness that his hard work for a CCIE has paid of.

Robert was tremendously kind in his feedback to me.  Well done to you my friend !! Its your hard work and determination that paid off :)

Email from Robert:

“Ruhann,

Yes, I am enjoying it so far and am enjoying the fact that I know have more free time for the family.
Now, for some feedback on my thoughts about routing-bits and how I used it.
I first heard of the Routing-Bits Handbook (back when it was short notes) over a year ago when reading a success story of someone who had passed the CCIE on INE’s IEOC and raved about how great it was and how much it helped. After reading some other feedback I bought your Handbook.

Form the start I was hooked. I read over the pdf for the first couple of weeks and wanted to bring it everywhere. So, I had my printing office at work print out a gbc bound copy so I can bring it everywhere I went. Before I went to bed, I would look over a chapter almost every night as a review. On trips, I would read it on the plane and at the airport, and when I needed to supplement my reading materials I referred to the Handbook. Also, when I wanted to review a topic that I might not have touched in a while, I looked over the Handbook first.
Its funny that at times there were topics that I did not find in the docCD right away (MPPE for example) and I would refer to the Handbook on where to find it in the docCD until I memorized it. Besides being very clear and concise, I loved the fact for every section you showed where it was in the docCD. Awesome! Every topic I read in the Handbook I can refer back to the docCD location in case I needed to reference it in the lab. And config sets too. Great! I thought of the handbook as a mini-docCD and loved it.   I would recommend the Routing-Bit Handbook to anyone going for the CCIE RS as the ultimate supplement.
Even though I have passed the lab, I feel this will come in hand for my job at times. If there is something I need a quick refresher on, I am sure to look over the Handbook. Now I eagerly await for your SP version as there are topics on that track I want to learn and get better at.
Many Thanks,

Rob Kosyluk CCIE #28368″

From my experience and based on most of the responses I have had from candidates who passed their CCIE, one thing is obvious. The time taken to prepare and complete a CCIE is like isolation. Its time away from the world, social and family life. And after passing there is this unique pleasure in the freedom to do the things you previously loved.

Until that bug start biting for a second CCIE…

EIGRP adjacency using a secondary IP

November 27, 2010

Consider the following statement from Cisco.com : “Routers do not form EIGRP neighbors over secondary networks.

A Routing-BitsHandbook candidate queried this last week, claiming the statement is misleading and that EIGRP will indeed form an adjacency using a secondary IP address under specific conditions.

Consider the following configuration. R1 connects to R2 using a back-to-back serial connection. Both S1/1 interfaces have a primary and a secondary IP address defined. The EIGRP processes only matches the secondary IP addresses.

R1#
interface Serial1/1
ip address 10.1.1.1 255.255.255.0 secondary
ip address 10.5.1.1 255.255.255.0
!
router eigrp 1
network 10.1.1.1 0.0.0.0
no auto-summary

R2#
interface Serial1/1
ip address 10.0.1.2 255.255.255.0 secondary
ip address 10.5.1.2 255.255.255.0
!
router eigrp 1
network 10.0.1.2 0.0.0.0
no auto-summary

So what do you think will happen in this scenario? Will R1 and R2 become adjacent? Cisco explicitly mentions that a secondary IP address is not used in the EIGRP hello packets, therefore EIGRP neighbors will not become adjacent using secondary IP addresses.

Congrats to Sasikumar, CCIE # 27312

October 28, 2010

I know I have not been posting much. Been busy with the content and all the email requests. But it is always inspiring to other candidates still studying to hear of other passing.

Sasikumar Sadayan from India started his everquest some months back and successfully completed his first CCIE. That earned him the ever climbing number 27312. His feedback:

“I  cleared my CCIE R&S this October 25th in Bangalore. Your R&S short notes was very helpful  and helped me a lot to get a quick snapshot of all the important topics in the exam. I browsed your ShortNotes three or four times before  the lab exam.

I would preserve this short notes for my life time. Please keep up the good work and  I would recommend this to everyone.
I want to use  this opportunity to thank my wife and kid  for their overwhelming support  in  getting this Certification.”

I find it very rewarding having played a really small part in someone else’s great achievement.

VRF-lite route leaking

September 13, 2010

The purpose of VRF-lite is to extend the logical separation of two different networks from a MPLS network down to a single CE router, connected to both these networks. It’s called VRF-lite because it is done without running MPLS (LDP/TDP) or MP-BGP between the PE and CE. Traffic is mapped to the VRF assigned to the ingress interface on the CE router.

But VRF-lite could be used without connecting to a MPLS network entirely! Consider what a VRF is?

A VRF is a mechanism used to provide logical separation between routing tables on the same router. It is locally significant to the router. Each interface on a router can only be assigned to one VRF, but a VRF can have multiple interfaces.

So VRF-lite could be used to separate multiple networks using the same equipment. (Not exactly something you should ever plan in a design, but it could be useful to know)

Once you have the separation you needed, you might need a way to selectively bridge that separation to allow communication between the VRF’s.

Assume the following scenario:

Output101- sh run vrf

September 4, 2010

Now that the hard work is behind me, the awesome holiday has past, I can finally get back to all the outstanding fun stuff. That said I have some good half completed posts are on the way :)

I came across the following command browsing the DOC-CD a couple months back, and I have used it ever since.

sh run vrf [vrf-name]

The show running vrf feature provides the option to display a subset of the running configuration on a router that is linked to a VRF instance. It can be used to display the configuration of a specific VRF or of all VRFs configured on a router. The command is unfortunately only available on the more recent IOS versions, but if available makes life easy.

Congrats to Matthew, CCIE #26439

July 13, 2010

I have not had much time lately for blogging between a new job, a new baby, an updated version to R&S Short-Notes and the new SP Short-Notes. Besides all that, I have the all important ‘free’ lunch for $1400 which will be served in few weeks time in RTP.

But in the midst of my current time challenge, I would like to congratulate the newest R&S CCIE on the block.

Matthew Smith, who from now on,  will be known as Matthew Smith CCIE 26439, successfully passed his R&S two days ago. Huge congratulations in conquering the hardest CCIE currently out there !!!! As always it is a great feeling to know I helped a little :)

This was his feedback.

“Hey – just wanted to say thanks for your awesome short notes. They certainly helped to get me over the hump and is perfect material for the day before the exam. This book will remain on my desk for years to come. Best of luck and thanks again!

Please feel to visit Matt’s blog and congratulate him : http://ccieforme.blogspot.com

Troubleshooting BGP

February 25, 2010

The new focus is of the R&S exam is troubleshooting. And for some reason this is seen as a new topic to study and as a result feared. It is vital to understand why troubleshooting was added to the lab, and why it will possibly be added to other tracks.  Anybody can apply vanilla configs, provided it is done without error, in the correct order, and by avoiding the question pitfalls.

Troubleshooting was introduced by Cisco to give the CCIE certification that edge it needs to seperate the guys that really understand the technologies and those that just learned to configure labs. Troubleshooting is thus NOT a new section! If you understand know each technology, understand its it building blocks, processes and states, troubleshooting should be nothing ‘new’.

That said, once you understand the work, drafting a troubleshooting methodology per technology should be fairly straight forward. A detailed troubleshooting approach is included in each chapter of the Routing-Bits Handbooks.

(Note ‘{ }’ curl-brackets indicate replaceable values, the rest is regex)

Troubleshooting BGP session start-up problems

1- Are you seeing the expected neighbors in a NON ‘idle’ or ‘active’ state?
#sh ip bgp summary

2- Is a sourced telnet to the neighbor address working?
#telnet {peer-ip} 179 /source {src-int-ip}

3- Confirm if the configuration is correct and matching to neighbors configuration?
#sh run | b router bgp

4- If eBGP, is the neighbor directly connected? (Should be 1 hop in the trace)
4.1- If not directly connected is multihop configured?
#trace {peer-ip} source {src-int-ip}
#sh run | i {peer-ip}.*ebgp-multihop

PfR Process flow

January 19, 2010

I came across a really good Performance Routing document, and I thought it should assist R&S v4 candidates. It has really great examples of the different scenarios along with implementations.

Here is a depiction of the PfR process flow for OER configuration:
