As a quick follow up to this: routes are exchanged, but they are not
emitted to the kernel.<br>

I am not seeing any Netlink route messages for any of the LSAs from
neighbor 192.168.10.3 (colored in red above).<br>
Could it be that when using an ipv4 channel with OSPFv3, Bird ought
to program these across address families?<br>
