Challenge Lab 20: Multi-Area OSPFv3 with PPP and Logging

Lab Objective:

The objective of this lab exercise is for you to configure OSPFv3 on three routers using more than one area. It’s a repeat of the previous lab but with PPP and logging added to make it a little trickier.

Lab Purpose:

Multi-Area OSPFv3, as well as PPP and logging, 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 9/10.

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 20: Multi-Area OSPFv3 with PPP and Logging 1

Task 1:

Configure the topology above but change all Serial links to use PPP with CHAP. Use the password cisco and device hostnames. 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:

Set RouterA to log to server 3fff:1234:aaaa:1::2/64 and the severity level should be “emergencies.”

Task 4:

Check your configurations with relevant show commands.

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. You can expect the same for logging and PPP.
