Hello You misunderstood what does 'secondary' option (with 'table master sorted'). This is relevant to outgoing routes only and allows to export the best route that passed the filter (but only one for each net). It does not alter the behavior for incoming routes, which is to keep just one received route for each net (i.e. replace one with the newer). Therefore, you cannot 'couple' both route servers using IBGP. OTOH, perhaps you don't need that - route servers are usually operated two independent, where each client is connected to both. The 'coupling' could be done by add-path extension (which allows to send or receive several routes for the same network over one connection), which is not yet merged to the BIRD. -- 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."
