You mean I can do:
protocol bgp XXX { neighbor; interface eth0; /* ... */ }
?
No, you need to specify neighbor link-local address (i probably misunderstood your point):
protocol bgp XXX { neighbor fe80::1 external; interface eth0; }
Oh, OK, not as convenient as specifying an interface. I wonder how FRR is getting the remote IP. Maybe it's automatically in the neighbor table due to neighbor advertisements?
For BGP autodiscovery, there are currently two drafts: draft-acee-idr-lldp-peer-discovery-05 draft-xu-idr-neighbor-autodiscovery-10 One could also do some hacks like listening for router advertisements. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
