As many of you already know I’ve been teaching our brand new Routing and Switching CCIE bootcamps for the past couple months. I’ve recently restructured the bootcamp in that mock labs are not done during the second week to allow for expanded coverage of the CCIE blueprint topics. The mock labs are now done after the bootcamp and I give every student 1500 tokens to schedule them. The new structure allows for roughly 100+ hours of hands-on demonstration using my own rack over the course of the two weeks. I start at 9am and go until roughly 8pm each night (Friday’s included). After 8pm the students usually go for dinner and start working on the labs and/or review for the next day. Every topic is covered hands-on by me during the two weeks. Students are given the R&S CCIE ATC Videos free of charge when scheduling the bootcamp because even with 100+ hours we do not have time to cover the basics.

As far as my teaching style goes Continue Reading

The whole INE team is happy to congratulate Rock Bassole, CCIE #28657! It was my personal pleasure to meet Rock in our CCIE R&S Bootcamps, and I’m glad to see him getting the so well-deserved CCIE title! Keep up the good work, Rock!

After many months of preparation, I finally passed the CCIE lab exam on April 14th. I want to thank INE for its great material that helped me in this preparation. I used the advanced technologies class on demand and the CCIE Workbooks VOL 1, 2 and 4 to deepen and perfect my knowledge. The CCIE Bootcamp was a nice and rewarding experience. It was a rich source of opportunity that allowed me to re-enforce the most important areas of the blueprint. A long side of the long days of hard work in Tampa, I had the opportunity to tie up new relationships in a relaxed and friendly atmosphere. Many thanks to INE Instructors for their precious advices and guidance. I finally want to thank my family and friends for their constant support. A page is now turned; hope to write another one, in the future, with INE.

Congratulations, Rock, and thank you for choosing INE to help you in pursuit of your goals! Everyone else – stay tuned for upcoming in-depth technical blog posts from INE!

I enjoyed Petr’s article regarding explicit next hop.  It reminded me of a scenario where a redistributed route, going into OSPF conditionally worked, depending on which reachable next hop was used.

Here is the topology for the scenario:

Last week we wrapped up the MPLS bootcamp, and it was a blast!   A big shout out to all the students who attended,  as well as to many of the INE staff who stopped by (you know who you are :) ).    Thank you all.

Here is the topology we used for the class, as we built the network, step by step.

The class was organized and delivered in 30 specific lessons. Here is the “overview” slide from class: Continue Reading

Clock_New Time is a valuable resource in the lab.   In a lab task, if asked to configure a policy-map named “BOB”, it doesn’t get the same point value if we happen to accidentally name it “bob”, especially  if they are looking to see if you configured what they asked for.

The challenge is, that when reviewing a lab task, and we discover that we need to change a name, it could be a hassle, as we need to remove the policy-map, recreate the policy map, and then put it in place again.

So if you are down to the last minute, here is a time saving solution, that can assist with that process.

IOS allows us to rename a policy-map, and the IOS will swap out the name in other areas of the configuration that reference that policy map. Continue Reading

Can you solve this puzzle?

R2, R3 and R4 create the service provider network, with MPLS on all three routers, and iBGP at the PE routers.  R1 and R5 are the CE routers.

R2, prefers the BGP next hop of 4.4.4.4 for network 5.5.5.5 (R5 loopback). R4, at 4.4.4.4 is an iBGP neighbor.

R2#show ip route vrf v | inc 5.5.5.0
B       5.5.5.0 [200/409600] via 4.4.4.4, 00:06:47

Is R2 preferring an iBGP learned route, which has an AD of 200, over a EIGRP route, which would have an AD of 90?

Can you identify why the routing for 5.5.5.0 on the VRF of R2 is using BGP instead of EIGRP?

Below are the relevant portions of the configuration, which also can serve as a great review of how to configure MPLS VPNs. Continue Reading

Are you ready to explore the following?

  • HSRP
  • VRRP
  • GLBP
  • NTP
  • DHCP
  • DNS
  • WCCP

Check out the latest chapter posted in the Advanced Technologies Class On Demand.

Next week watch for the final chapter on Network Optimization, where we explore such critical Version 4 topics like EEM, IP SLA, and much more.

Also, soon here on the blog site, watch for a Video Blog episode that discusses study and lab exam strategy for the massive body of knowledge that is IP Services/Optimization in general.

“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.

ZBF Transparent VRF R2

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

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.

BGP Triangle
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
