If they are on different ifaces (like in your example), you can have multiple interface statements in one BFD instance. But in general, you can specify BFD parameters also directly in BGP protocol as options of 'bfd' switch: https://bird.network.cz/?get_doc&v=20&f=bird-6.html#bgp-bfd protocol bfd { } protocol bgp { ... bfd { min rx interval 1000000 us; min tx interval 1000000 us; }; } -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@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."
