Thanks, Alexander Using bird 2.0.2. Guess it does not include patch you mentioned
Have another question: Configured peers in vrf with different addresses but still in overlapping subnets. BGP session are established and some prefixes advertised. The issue is that bird/bgp tries to resolve nexthops for all vrfs only in default. ip -4 neigh show vrf vrf01 190.34.32.101 dev swp32.101 lladdr 00:00:80:8f:c3:1a REACHABLE ip -4 neigh show 190.34.32.101 dev swp32 INCOMPLETE ip route show vrf vrf01 134.0.0.0/24 via 190.34.32.101 dev swp32 proto bird metric 32 .-- Semion Lisyansky On Sun, Nov 4, 2018 at 8:11 PM Alexander Zubkov <gr...@qrator.net> wrote: > Hi, > > What version of bird you are using?
