120 Labs for Cisco CCNA 200-125 and CCENT Exams

Challenge Lab 18: OSPFv3

Lab Objective:

The objective of this lab exercise is for you to configure OSPFv3 static routing.

Lab Purpose:

Configuring OSPFv3 is a CCENT exam subject so you can expect to find it in the exam. I have provided show runs and test commands where appropriate.

Certification Level:

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

Lab Difficulty:

This lab has a difficulty rating of 6/10.

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. Check that you can ping across the Serial link.

Task 2:

Configure OSPFv3 on both routers. Put all networks into area 0. Make the router id for RouterA 1.1.1.1 and RouterB 2.2.2.2.

Task 3:

Check your IPv6 routing table. Ping the Loopback interfaces on RouterB from RouterA.

R1#ping ipv6 2001:ABCD:AAAA:1111::1 

Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 2001:ABCD:AAAA:1111::1, timeout is 2 seconds:
