Lab Objective:
The objective of this lab exercise is for you to learn how to configure EIGRP running IPv6.
Lab Purpose:
EIGRP for IPv6 will allow you to run a distance vector routing protocol in your infrastructure when running IPv6. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to implement EIGRP on an IPv6-enabled network.
Certification Level:
This lab is suitable for ICND2 certification exam preparation.
Lab Difficulty:
This lab has a difficulty rating of 7/10.
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 20 minutes.
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure hostnames on R1, R2, R3, and R4 as illustrated in the topology.
Task 2:
Configure each router with its respective IPv6 addresses and Gigabit interfaces, and make sure that your router is ready to route IPv6 traffic.
Note: You can select the Gigabit interface you want to use (Gig0/0 or Gig0/1) for any network shown in the diagram.
Task 3:
Configure EIGRP for IPv6 in the network as follows:
- All the routers will be inside ASN 100;
- There are no IPv4 addresses at all so manually create a router ID for each router (different on each unit); and
- Make sure that you advertise every network shown in the diagram (including Loopbacks).
Task 4:
Make sure that you can ping from R2 Loopbacks to R4 Loopbacks to ensure that there is full connectivity.
Task 5:
To see the EIGRP database, provide the following information from R1:
- show ipv6 eigrp neighbhors
- show ipv6 eigrp topology
- show ipv6 route
Configuration and Verification
