Topology
Notice!
IPv6 addresses have changed. Follow the below topology diagram and tasks to accomplish the goals.
Pic1. IPv6 Topology Diagram.
Task 1
Remove all RIPng configurations. In the upcoming tasks, follow the addressing scheme using RFC 4193 presented in the topology diagram above.
Task 2
Configure IPv6 addresses as follows:
R1 Serial0/0
- FC00:1:1:7B::1/64 (global)
- FE80::1 (link-local)
R2 Serial0/0
- FC00:1:1:7B::2/64 (global)
- FE80::2 (link-local)
R3 Serial0/0.123
- FC00:1:1:7B::3/64 (global)
- FE80::3 (link-local)
Task 3
Enable IPv6 address on Loopback 0 of R1, R2, and R3. Use the address FC00:A:A:A::x/128 where 'x' is the router number.
Task 4
Enable EIGRP AS 1 on the NBMA network between R1, R2 and R3. Ensure IPv6 connectivity between the loopbacks of R1, R2, and R3.
Solution
Task 2
Configure IPv6 addresses as follows:
R1 Serial0/0

R2 Serial0/0
- FC00:1:1:7B::2/64 (global)
- FE80::2 (link-local)
R3 Serial0/0.123
- FC00:1:1:7B::3/64 (global)
- FE80::3 (link-local)
