Call for testing: bird as VPN route reflector

[Allan Pinto]

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
