BGP: Allow to specify interface for regular sessions
This may be useful if multple interfaces share the same network range. Thanks to Fritz Grimpen for the original patch.
How does this fix the issue of incoming connections. We still have a single listener on port 179 and if we have multiple interfaces with same IP Address, we will still have a problem locating the protocol ? I am trying to understand where we set sk->iface that is being used in bgp_find_proto() in this line (p->cf->iface == sk->iface))).
