Lab 196 - EIGRPv6 NBMA Network

Prerequisites: CCNP level skills.

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
  • 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 R1R2, and R3. Use the address FC00:A:A:A::x/128 where 'x' is the router number.

R1 Config:
!
interface Loopback0
 ip address 10.0.1.1 255.255.255.0

R2 Config:
!
interface Loopback0
 ip address 10.0.2.2 255.255.255.0
 ipv6 address FC00:A:A:A::2/128
!

R3 Config:
!
interface Loopback0
 ip address 10.0.3.3 255.255.255.0
 ipv6 address FC00:A:A:A::3/128
!

Task 4
Enable EIGRP AS 1 on the NBMA network between R1R2 and R3. Ensure IPv6 connectivity between the loopbacks of R1R2, and R3.

R1 Config:
!
ipv6 unicast-routing
!
