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:
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.
