Challenge Lab 19: Multi-Area OSPFv3

Lab Objective:

The objective of this lab exercise is for you to configure OSPFv3 on three routers using more than one area.

Lab Purpose:

Multi-Area OSPFv3 is a core ICND2 topic. I have provided show runs and test commands where appropriate.

Certification Level:

This lab is suitable for both ICND2 and CCNA certification exam preparation.

Lab Difficulty:

This lab has a difficulty rating of 8/10.

Readiness Assessment:

When you are ready for your certification exam, you should complete this lab in no more than 15 minutes.

Lab Topology:

Please use the following topology to complete this lab exercise:

Challenge Lab 19: Multi-Area OSPFv3 1

Task 1:

Configure the topology above. Test by pinging from RouterA to RouterB, then RouterB to RouterC. You will not be able to ping from A to C until you have configured OSPFv3.

Task 2:

Configure OSPFv3 between all routers with each interface/subnet in the correct area. Add the router id manually.

Task 3:

Check your configurations.

Solution

OSPFv3 is a core CCNA topic, and because it’s one of the new additions, you can expect it to be featured in the exam.
