But even in that case kernel should know where to send packets
for 80.96.148.1 . Perhaps there is some route to that address?
What is your routing table?

What is a traceroute to 80.96.148.1 from that host? If there is more
hops you should set multihop option.

If BIRD didn't found appropriate iface, it didn't started the BGP protocol.
Even if it would listen to port 179 (for example, if there is another
proper BGP protocol), it wouldn't accept session from that IP because
it wouldn't know the iface.
