correction: the error message is not related particularly to bird but seems related to this issue in latest freebsd release: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275341 Once fixed though, I have the same results. routes are not applied to the kernel. ospfv3. Applying a `/31` to the point to point interface: ``` vlan200: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 150 0 options=4600703<RXCSUM,TXCSUM,TSO4,TSO6,LRO,RXCSUM_IPV6,TXCSUM_IPV6,MEXTPG> ether 9a:c7:bd:e8:62:dc inet 10.200.1.1 netmask 0xfffffffe broadcast 255.255.255.255 inet6 fe80::98c7:bdff:fee8:62dc%vlan200 prefixlen 64 scopeid 0x4 groups: vlan vlan: 200 vlanproto: 802.1q vlanpcp: 0 parent interface: iavf0 media: Ethernet autoselect (10Gbase-SR <full-duplex>) status: active nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> ``` allows the route to be shared .

I get the same result as well. On freebsd when starting I also get this message " Cannot find next hop address".

Hoi,

As a quick follow up to this: routes are exchanged, but they are not emitted to the kernel. root@vpp0-2:~# birdc show ospf state BIRD 2.14 ready.

Could it be that when using an ipv4 channel with OSPFv3, Bird ought to program these across address families?
