Peer-group is not working

[amanchoubey19901]

Hi Team,

i am trying to configure the bgp peer-group,but it's showing idle state.

i have 4 routers(7200).I have configure the loop back ip and i am trying to configure the peer with that loop back.

can someone suggest me to resolve the issue?

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
3.3.3.3 4 5500 0 0 1 0 0 never Idle
4.4.4.4 4 5500 0 0 1 0 0 never Idle
5.5.5.5 4 5500 0 0 1 0 0 never Idle

i am trying to configure like this:-

neighbor IBGP_PEERS peer-group/remote-AS/next-hop-self/update-source loopback1

thanks in advance.

Hello,

Have you set the neighbor X.X.X.X update-source LoX on the neighbors? 

Please share the bgp configuration from 2 routers and the "show ip route" so we can understand what is going on.

Thanks,

ADP

Hello,

make sure your config looks similar to the one below:

router bgp 5500
neighbor IBGP_PEERS peer-group
neighbor IBGP_PEERS remote-as 5500
neighbor IBGP_PEERS update-source loopback 1
neighbor 3.3.3.3 peer-group IBGP_PEERS
neighbor 4.4.4.4 peer-group IBGP_PEERS
neighbor 5.5.5.5 peer-group IBGP_PEERS

Also make sure the loopback interfaces are reachable (either through static routes or through an IGP)...
