I have the following config that works in BIRD 2.18, when I attempted to upgrade and run 3.2.1 it exits out on the below. This appears to happen with both IBGP and EBGP peers. I'm assuming its because IPv4/IPv6 AFI's are on the same transport session... Just trying to figure out the correct "fix" here for BIRD3 ... bird[20990]: rserv1: Missing next hop address template bgp BH_CLIENT { local as MYAS; source address MYIP; ipv4 { import keep filtered on; import filter CLIENT_IN; export filter CLIENT_OUT; }; ipv6 { import keep filtered on; import filter CLIENT_IN; export filter CLIENT_OUT; }; } # protocol bgp rserv1 from BH_CLIENT { neighbor 2000:f000:1::10 as MYAS; source address MYIP6; ipv4 { import none; export none; }; ipv6 { import none; export none; }; }
