Hello, we have encountered a different ibgp behavior between bird 1.6 and bird2, and I am not sure if it's an intentional change in bird2 or a bug. Let's consider the following topology:
192.168.1.0/24 192.168.2.0/24 R1 ------- ebgp ------- R2 ------- ibgp ------- R3 .2 .1 .1 .2
R1 uses AS 65001, R2 and R3 uses AS 65000. R1 propagates some routes (e.g. 10.10.10.0/24) via eBGP to R2, which sends them to R3 via iBGP. bird2 config on R3:
template bgp IBGP { local as 65000; direct; ipv4 { next hop self; import keep filtered on; import all; }; }
protocol bgp from IBGP { neighbor 192.168.2.1 as 65000; }
What bird is config on R2? I don't think there are any intentional changes w.r.t. your config. -- 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."
