How to Master CCIE Routing and Switching V5.1 Foundations: Practical 32

If you are preparing for the CCIE Routing and Switching written and lab exams, you might be wondering how to bridge the gap between the CCNP and CCIE level of knowledge and skills. One of the best resources to help you with this challenge is the book CCIE Routing and Switching v5.1 Foundations: Bridging the Gap Between CCNP and CCIE by Narbik Kocharians.

This book covers all the topics in the CCIE Routing and Switching blueprint in depth, with clear explanations, diagrams, and configuration examples. It also includes hundreds of practical exercises that test your understanding and reinforce your learning. One of these exercises is Practical 32, which focuses on OSPFv3 routing.

In this article, we will walk you through the steps to complete Practical 32 successfully. You will learn how to configure OSPFv3 on multiple routers, verify the routing table and neighbor adjacencies, troubleshoot any issues, and optimize the network performance. By the end of this article, you will have a solid grasp of OSPFv3 routing and how to apply it in real-world scenarios.

Practical 32: OSPFv3 Routing

The topology for Practical 32 is shown in the figure below. It consists of six routers (R1 to R6) connected by various links. The goal is to configure OSPFv3 on all routers and ensure full connectivity between them.

The following are the requirements for this exercise:

All routers must run OSPFv3 with process ID 1.

All interfaces must be in area 0.

All interfaces must use IPv6 addresses from the 2001:DB8::/64 prefix.

All interfaces must use link-local addresses for OSPFv3 neighbor discovery.

All routers must use their router IDs as their loopback addresses (e.g., R1's loopback address is 1.1.1.1).

All routers must advertise their loopback addresses into OSPFv3.

All routers must form full adjacencies with their directly connected neighbors.

All routers must have full reachability to all other routers' loopback addresses.

All routers must use the lowest cost path to reach any destination.

No static routes or default routes are allowed.

Step 1: Configure IPv6 Addresses

The first step is to configure IPv6 addresses on all interfaces according to the topology diagram. For example, on R1, we can use the following commands:

R1(config)# interface loopback0

R1(config-if)# ipv6 address 1:1:1::1/128

R1(config-if)# exit

R1(config)# interface ethernet0/0

R1(config-if)# ipv6 address 2001:DB8::11/64

R1(config-if)# exit

R1(config)# interface ethernet0/1

R1(config-if)# ipv6 address 2001:DB8::12/64

R1(config-if)# exit

We can repeat the same process for all other interfaces on R1 and all other routers. We can verify the IPv6 addresses using the show ipv6 interface brief command. For example, on R1, we should see something like this:

R1# show ipv6 interface brief
