The objective of this lab exercise is for you to learn and understand how to manually configure OSPFv3, which is a core ICND2 and CCNA topic.
Manually configure IPv6 interface addressing and then configure a Single-Area OSPFv3 connection.
This lab is suitable for ICND2 and CCNA certification exam preparation.
This lab has a difficulty rating of 7/10.
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes.
Please use the following topology to complete this lab exercise:
Configure hostnames on routers R1 and R3 as illustrated in the topology.
Configure the IPv6 addresses on the FastEthernet interfaces of R1 and R3 as illustrated in the topology.
Enable OSPF in area 0 between R1 and R3. For R1, use OSPF process ID 1. For R3, use OSPF process ID 3. Configure router ID 220.127.116.11 for R1 and 18.104.22.168 for R3.
Ping across the link and then use the relevant show commands to verify your configurations.
Configuration and Verification
For reference information on configuring hostnames, please refer to earlier labs.
