It is an IBGP peering using loopback as source. This is not a scenario that I c
ame across but something I just thought of.

Subject: Re: Passive interface command for BGP peering?
Dave,
i see that you're using the loopback to peer.
is is prohibited to use the physical (primary) interface's IP address for
peering?

from activating the BRI link but that will not stop BGP peering when some other
interesting traffic activates the link. I tried access-list extended out block
ing tcp port 179 at the BRI interface but the IBGP peering (thru loopback inter
face) still occurs. I think it is because the access-list cannot block locally
generated traffic. Hope someone can advice.
