Lab 212 - IPv6 MP-BGP

Prerequisites: CCNP level skills.

Topology

Pic 1. Topology Diagram.

Task 1
Using previous lab's IPv6 configuration, create new loopback interface on R1 and SW2. Use the following IPv6 addresses:

• R1 - Loopback1 = 2002:a00:101:1111::1/128
• SW2 - Loopback1 = 2002:a00:101:8888::8/128

Task 2
Enable IPv6 MP-BGP peering between R1 (AS100) and SW2 (AS800). Advertise IPv6 addresses configured on Loopback1 interface of both devices into IPv6 MP-BGP. Check the connectivity.

Solution

Task 1
Using previous lab's IPv6 configuration, create new loopback interface on R1 and SW2. Use the following IPv6 addresses:

• R1 - Loopback1 = 2002:a00:101:1111::1/128
• SW2 - Loopback1 = 2002:a00:101:8888::8/128

R1 Config:
!
interface Loopback1
 no ip address
 ipv6 address 2002:A00:101:1111::1/128
!

SW2 Config:
!
interface Loopback1
 no ip address
 ipv6 address 2002:A00:101:8888::8/128
!
  
Task 2
Enable IPv6 BGP peering between R1 (AS100) and SW2 (AS800). Advertise IPv6 addresses configured on Loopback1 interface of both devices into IPv6 MP-BGP. Check the connectivity.

R1 Config:
!
router bgp 100
 no synchronization
 bgp log-neighbor-changes
 neighbor 2002:A00:101:D7::8 remote-as 800
 no neighbor 2002:A00:101:D7::8 activate
 no auto-summary
 !
 address-family ipv6
  neighbor 2002:A00:101:D7::8 activate
  network 2002:A00:101:1111::1/128
 exit-address-family
!

NOTICE!
The configuration of IPv6 address family may be different on your router. It depends on the IOS version you use (neighbor and network statements should be configured in ipv6 address-family but may show like in my example).

SW2 Config:
!
router bgp 800
 no synchronization
 bgp log-neighbor-changes
 neighbor 2002:A00:101:D7::1 remote-as 100
 no neighbor 2002:A00:101:D7::1 activate
 no auto-summary
 !
 address-family ipv6
  neighbor 2002:A00:101:D7::1 activate
  network 2002:A00:101:8888::8/128
 exit-address-family
!
