Hello Ondrej,
Did you have a chance to check out the patch? I am happy to adjust it
if needed.
Hello Luiz,
have you tried netlink flavour of BIRD ? It requires FreeBSD 13.2, but
should work out of the box in such a setup, I have not tested though.

Hello,
While experimenting in FreeBSD 13.1 with IPv4 over IPv6 nexthop
routes, I
realized that BIRD was unable to read routes from the kernel as well as
export routes to the kernel. The support for it was implemented in
FreeBSD
13.1 [1].
I have attached a patch that made it work for me on FreeBSD 13.1, both
importing and exporting to/from kernel. I believe the patch will
still need
some work, as from a quick look, OpenBSD still has no support for
it. I'm
happy to implement any suggested improvements and send a v2 of it.
Hello
This looks particularly simple. Will check that.
