hello, i have an interface with a /64 address configured: # ifconfig bridge0.500 bridge0.500: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=0 ether 58:9c:fc:10:8d:b4 inet6 fe80::1%bridge0.500/64 scopeid 0x1c inet6 fd13:480d:2ffa:3::1/64 groups: vlan vlan: 500 vlanproto: 802.1q vlanpcp: 0 parent interface: bridge0 nd6 options=1<PERFORMNUD> this is configured as an OSPF stub interface in BIRD: protocol ospf v3 core { area 0 { interface "bridge0.500" { stub yes; }; ... however, BIRD only adds a /128 route into the OSPF database: # birdc show route in fd13:480d:2ffa:3::/64 BIRD 3.2.0 ready. Table master6: fd13:480d:2ffa:3::1/128 unicast [core 13:25:02.965] ! I (150/0) [176.126.243.164] dev bridge0.500 fd13:480d:2ffa:3::/64 unicast [direct1 13:38:01.578] * (240) dev bridge0.500 i would have expected it to add the /64 route instead. filtering the /64 route in the direct protocol does not make any difference, except that the direct route disappears from 'show route'. am i doing something wrong? the entire configuration is here: https://www.le-fay.org/tmp/30d/bird.conf using BIRD 3.2.0 on FreeBSD 15.0.
