Lab 29: IPv6 BGP

Configure IPv6 addresses and EIGRP as IGP on all routers. Then enable IPv6 unicast-routing and BGP on R1 and R2:

ipv6 unicast-routing

router bgp 10
 no synchronization
 bgp router-id 1.1.1.1
 bgp log-neighbor-changes
 neighbor 2002:2222::2 remote-as 20
 neighbor 2002:2222::2 ebgp-multihop 2
 neighbor 2002:2222::2 update-source Loopback1
 no auto-summary
 !
 address-family ipv6
  neighbor 2002:2222::2 activate
  network 3002:1111::/64
 exit-address-family

After the configuration, here is R2's BGP routing table:

R2#show ipv6 route bgp
IPv6 Routing Table - 7 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
       U - Per-user Static route, M - MIPv6
       I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary
       O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
       ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
       D - EIGRP, EX - EIGRP external
B   3002:1111::/64 [20/0]
     via 2002:1111::1

As a result, you can ping R1's Loopback 1 address from R2:

R2#ping 3002:1111::1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3002:1111::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/20/32 ms
