Thomas Fischer, CCIE #26636 – Routing & Switching
I am proud to let you know, that I passed my CCIE R&S Lab in Brussels on Aug. 5th. This was my second attempt. I want to express my deepest appreciation for your Products. I am a self-paced student, using Vol1 (*****), Vol2 (****) and Vol4 (***). Thanks INE, it feels so good to have a social life again

Matthew Ayre, CCIE #26654 – Service Provider
Big shout out for INE and their OEQ / lab preparation resources! I just cleared service provider on second attempt finishing about an hour and a half early. Was ~7% of passing the first time using INE 1 & 2 as my primary material then just drilled down on the finer details reading theory. The workbooks really developed the speed and confidence required to beat the exam!
Prateek Madaan, CCIE #26772 – Security
Had been a long and tough journey. Would really like to thank INE from the Core of my heart for facilitating in imparting the skills required not to just pass the exam but to DESERVE it as well…
There are many workbooks available which I prepared along with INE , do not want to name or list any one of them…or make any comparisons…But in comparisons INEs Security Workbooks may sound tough as compared to others BUT once you go through these workbooks is when you actually feel DESERVED the tag rather than just passing it.. Each of these workbooks and the tasks test each and every technology in detail and till the dead end….
In my last attempt on Version 2 I was deprived of the number by 1%, still followed and trusted INE workbooks and finally it helped….Today I am more happy not to procure the number but to actually have the feeling of confidence that ‘YES this time I deserve to be a CCIE’ and all due to the exhaustive INE workbooks….
Update!
Olusegun Olurotimi Medeyinlo, CCIE #26683 – Routing & Switching
I the Passed the CCIE R&S lab in Brussels on my Second attempt. I’d like to thank the instructors at INE for their excellent workbooks and blogs. Special thanks to Keith Barker for his encouragement and advice.
Now, I have my own CCIE number #22683.
Congratulations to everyone who passed the CCIE Lab Exam. Our instructors, authors, and staff have been committed to helping you pass your exam for the past seven years and we will continue to make your exam our number one priority. Only at INE.

For the latest Video Blog – simply click the link below:
This Video Blog demonstrates and discusses uses for this powerful rack rental tool.
During this video I mentioned that it is now possible to view and download your saved configs, but I forgot to show from where. The location is shown below. Enjoy!
“Why doesn’t this PING work!?!”
Here is a simple 3 router configuration, well at least it is simple on 2 of the 3 routers. R1 and R3 are configured quite traditionally, but R2 is a bit more involved.
Here is the diagram.
Here are the details.
R2 is using a VRF which includes both LAN interfaces. R2 is also acting as a Zone Based Firewall in transparent mode, allowing all ICMP traffic in both directions, as well as SSH from the inside to the outside networks. R2 has a bridged virtual interface in the 10.123.0.0/24 network. All are running OSPF, but pings issued from R2 to the loopbacks of R1 and R3 are failing.
Can you identify why? Continue Reading

RFC, or Request for Comments, are documents published that describe various items surrounding computer networking. Generally, these are memorandums published by the Internet Engineering Task Force.
RFCs can be a great resource. For some unknown reason, most candidates preparing for the CCIE don’t take the time to review these documents, which can be very helpful in assisting with understanding the how and why of various networking components. Perhaps the language is a bit dry, or they prefer books with shiny covers.
Recently, there have been a lot of talks around LISP – location and Identity Separation Protocol. This is a “new” technology aiming to resolve some of the Internet scalability issues and which has been implemented in IOS 15.x. In this blog publication we are going to give a general overview of LISP, pointing out benefits as well as drawbacks of the technology.
Hierarchical Routing and its Problems
Ever since ARPANet has been launched, routing in packet switched networks (PSNs) has been based on hierarchical network addressing to achieve scalability. The groundbreaking work by Kleinrock and Kamoun named “Hierarchical Routing for Large Networks, Performance Evaluation and Optimization” ([KLEIN]) clearly outlined all ideas of hierarchical routing. The main result of this work is that for a network of arbitrary connected N nodes it is possible to devise a hierarchical clustering scheme where nodes inside a single cluster only have to know routes to the nodes in the same cluster and other clusters, provided that addresses are assigned to the nodes following the hierarchical structure. The routing is assumed to be classic shortest-path selection process. Under optimal partitioning scheme, the size of routing table on every router would be of order O(log(N)).

Summer was in full swing, and it was over 105 degrees Fahrenheit outside. Bob was told it was a “dry heat”, but he thought “so is my oven”. Needless to say, Bob was glad to be in the data center, where the temperature and humidity controls kept it very cold. He had been asked to setup up a basic route-map with BGP, and here is the diagram he worked from.
The goal, was to modify BGP, so that all traffic going towards the 1.1.1.0 network (which is sourced from AS1), traveling either from or through AS23, would only use the 13.0.0.0/24 segment (between R3 and R1), and not use the 10.0.0.0/24 segment (between R2 and R1) as a transit path.
Bob reviewed some of the BGP topics he had recently learned. Here is the list he made of possibilities: Continue Reading

It isn’t my fault, they configured it that way before I got here! That was the entry level technician’s story Monday morning, and he was sticking to it.
Here is the rest of the story. Over the weekend, some testing had been done regarding a proposed BGP configuration. The objective was simple, R1 and R3 needed to ping each others loobacks at 1.1.1.1 and 3.3.3.3 respectively, with those 2 networks, being carried by BGP. R2 is performing NAT. The topology diagram looks like this:
The ping between loopbacks didn’t work, but R1 and R3 had these console messages:
R1# %TCP-6-BADAUTH: No MD5 digest from 10.0.0.3(179) to 10.0.0.1(28556) (RST) Continue Reading
