Hi Alexander, it has worked successfully acting as a vpn RR, have attached the diagram used as the setup, now if only mpls multicast vpn arrives i could replace my cisco box as the RR. :) , is it now possible in BIRD to have VRF interfaces? below setup, tell me if you need more details i can provide them later. the cloud is a linux box [slitaz] with bird acting as a vpnv4 RR, <-- loopback 5.5.5.5 R1 acts as a PE router for VRF AAA <-- loopback 1.1.1.1 R2 is a plain P router passing ldp <-- loopback 2.2.2.2 R3 is another PE router for vrf AAA <-- loopback 3.3.3.3 on linux i made the loopback under lo:1 but in the bird ospf configuration, the interface should still be mentioned as lo not lo:1 (wasted half an hour on this) bird --> R1 --> R2 --> R3 . <-- all four are connected through ospf R1 and R3 make the bgp neighbourship with BIRDbox , VRF AAA created on R1 and R3 with two loopback interfaces on each router and one addnl sub-interface on R3 under VRF AAA. below is some output from R1, R1#ping vrf AAA 13.13.13.1 Type escape sequence to abort.
