Dear all, Since some of our customers have devices which are not supporting EBGP add-path capability, I was wondering would there be an option that BIRD announces also other “not only best” paths, since it looks like that now only the best one elected, based on (router-id) RID is announced to the other customers (customers have normally 2 devices connected and announce the same prefixes) RID would be tie breaker as all the other attributes are the same. BGP RS Best Path Selection: * Prefer route with the highest Local Preference attribute. * Prefer route with the shortest AS path. * Prefer IGP origin over EGP and EGP origin over incomplete. * Prefer the lowest value of the Multiple Exit Discriminator. * Prefer routes received via eBGP over ones received via iBGP. * Prefer routes with lower internal distance to a boundary router. * Prefer the route with the lowest value of router ID of the advertising router. I don’t know if there would be something like Cisco based command: bgp bestpath as-path multipath-relax Thanks. Best regards, Nemanja Milovancevic

No, that is not supported. We may consider something like that in the future, but definitely not before transition to BIRD 3.0. -- 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."
