In the first part of this series, we subdivided the processes of EIGRP into four discrete steps, and detailed troubleshooting the first two. This is taken from the 5-Day CCNP bootcamp:

  • Discovery of neighbors
  • Exchange of topology information
  • Best path selection
  • Neighbor and topology table maintenance

Let us now discuss path selection and maintenance troubleshooting.

We should all remember that we can view the topology table of EIGRP with the command show ip eigrp topology. Here we can see the successor routes (these are the best routes that are placed in the routing table) and we can see the second best routes, the feasible successor routes. These feasible successor routes are the key to the lightening fast convergence that EIGRP can offer us. When a speaker loses its successor, it can quickly install a feasible successor route in its place.

We need to remember the important rule of feasible successors. The advertised distance of the proposed feasible successor must be less than the feasible distance of the current successor route. This is actually a loop prevention mechanism.

We are so excited here at INE for the live, online 5-Day CCNP bootcamp that starts Monday, August 16, 2010 . I look forward to seeing many of our aspiring CCIE candidates in this course. These students realize that they really need to improve their foundation Tier 1 knowledge as they seek to conquer the Lab Exam beast.

In this blog post, we are going to provide a sneak peek into some of the awesome information shared in the TSHOOT section of the bootcamp regarding the Troubleshooting of EIGRP. This can prove critical in the Troubleshooting and Configuration sections of the CCIE R&S Lab Exam, as well as the TSHOOT CCNP exam (duh!).

Where Is My Neighbor!?!?!?

Where Is My Neighbor!?!?!?

The first thing that you want to master when it comes to troubleshooting EIGRP is the ‘workflow” that EIGRP follows in its operation. We can subdivide the processes of this exciting protocol into four discrete steps:

  • Discovery of neighbors
  • Exchange of topology information
  • Best path selection
  • Neighbor and topology table maintaince

Our student and friend Deepak Arora was kind enough to share these sample TSHOOT exam questions in the IEOC.Thanks again, Deepak!

Enjoy everyone. The interface is pretty self explanatory, and as you can see, Cisco is combining several previous flash-based, written exam elements into one here. If you do need assistance with it, I copied the instructions link here as well.

We are working hard on the exciting new TSHOOT course, and yes, it will be made available free of charge to all of our existing CCNP students as part of our Investment Protection Program.

Also, we will be announcing a date of release soon.
