The boxes are sitting right next to each other, connected over an OpenBSD LACP trunk. I have made the pf rules as simple as possible: table <my_router_interfaces> counters {self} table <bsd_friends> counters {192.0.2.1,2001:DB8::1} pass in quick proto {tcp,udp,icmp} from <bsd_friends> to <my_router_interfaces> modulate state pass out quick proto {tcp,udp,icmp} from <my_router_interfaces> to <bsd_friends> modulate state The bgpd config is also simple: MY_ROUTER_ID_V4="192.0.2.2" MY_ROUTER_ID_V6="2001:DB8::2" MY_ASN="64515" AS $MY_ASN router-id $MY_ROUTER_ID_V4 rde med compare always network inet connected network inet6 connected group its_internal_v4 { remote-as 65515 announce IPv6 none neighbor 192.0.2.1 { local-address 192.0.2.2 descr "EXT-V4-R2" } } group its_internal_v6 { remote-as 65515 announce IPv6 none neighbor 2001:DB8::1 { local-address 2001:DB8::2 descr "EXT-V6-R2" } }
