Hi,
new bird / BGP user here, please bear with me :)
Consider a scenario with a bird box acting as (one of several possible) gateway for a set of clients, while having an iBGP and/or upstream BGP connection where the "real routes" come from.
Towards the client(s) a default route should be announced.
Is it possible to make the client default route announcement depend on at least one of the upstream peers (iBGP, real upstream) being "up" and having sent us all its routes? Or, even more ideally, one of them being up, having sent all its routes, _and_ bird having gotten around to installing them all in the kernel (data plane)?
No, that is not currently possible directly in BIRD. You could make some shell scripts that tracks state of BGP sessions and/or number of routes and enable/disable a static protocol with default route. -- 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."
