Bgp IPV6 peering update loopbak

[antonio gualtieri]

Hi guys, 

i have a question for you. If it's possible of course. 

I have some problems setting BGP in ipv6 environment. I have this sample configuration

Router:1
conf t
ipv6 unicast routing
router bgp 1
bgp router id 192.168.0.1
neighbor 2::2 update-source loopback 0

address family ipv6
neighbor 2::2 activate (loopback 0)
network 11::11/128 (loopback 1)

Router 2

conf t
ipv6 unicast routing
router bgp 2
bgp router id 192.168.0.2
neighbor 1::1 update-source loopback 0

address family ipv6
neighbor 1::1 activate (loopback 0)
network 22::22/128 (loopback 1)

In Gns3 i test it with C7200 iso but don't work !!!

We can help me?

Best regards

First can you ping between router for ipv6? 

[antonio gualtieri]

Yes i ping all routers on serial with ipv6 address 2001:1::1/64 for the first router and 2001:1::2/64 for second router, but the bgp protocollo don't execute adjacency 

[MHM Cisco World]

Ok' 

Neighbor <ipv6> remote-as xx

I dont see this command 

[antonio gualtieri]

You are right, I forgot to write it down. Sorry

[MHM Cisco World]

No since as is different you and multi hop away you need 

Neighbor <ipv6> ebgp multihop

[antonio gualtieri]

Ok I try it and update

[antonio gualtieri]

Sorry, dont work probably gns3 have a bug on ios on 7200

Can I see the config ? all config.

Do you ping from lo to lo 

You need to use source in ping command

The issue its multihope setting dont work !!! 

[MHM Cisco World]

As I mention in my first comment'

Where is static or igp route between two routers? The loopback must be appear in rib then you can use bgp'

lo must ping to other lo

The bgp not like other igp' it need first ip reachability between two peers.

[antonio gualtieri]

Thank you works correctly!!!IGP with OSPFv3 

[MHM Cisco World]

You are so welcome 
Have a nice day
