Thank you for the information. Tis didn't work but I think that 2.16 is probably missing a way to set the IP correctly on freebsd. This is probably missing that patch : https://gitlab.nic.cz/labs/bird/-/commit/e0ed978e753c57b65b89e860b49fd29acb0b43ad to make it works. Would be good to have a 2.16.1 that includes it.

Should I pass the vlan as ptp or stub on freebsd ? Or is there any other way to have unnumbered interfaces on freebsd?

I have no proper exp. with *bsd but from what I've heard:

* If you want unnumbered interfaces,then do you have a /32 assigned to
loopback?
* Ensure this address used as preferred source address (pref_src(?))
within the kernel protocol
* don't use stub. IIRC, stub means: do not send and do not participate.
* for unnumbered interfaces you want to use broadcast to send your pkts
to the multicast address

I hope I'm not totally off. Have a nice time...
