Hello BIRD currently does not check or use link up/down state. OSPF routers generally check reachability using HELLO packets, not by reported link state, although sometimes this is also implemented. Drawback of HELLO protocol (to check reachability) is that it has some timeout to find out that the neighbor became unreachable. By default, it is ~ 40 seconds, But it is possible to configure it to < 10 seconds (see hello/wait/dead interface options). -- 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."
