Yes, i suspected something like that. Generally, when the interface is created or bringed up, link-local address is automatically assigned, but it is marked as tentative, which BIRD ignores. We should probably wait until the the tentative flag for link-local address is removed. I think it probably tries to bind a socket on that tentative address, which fails (although that should be logged). -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: [email protected]) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
