to follow up on this (in case anyone else is following along at home), it turns out this behaviour depends on the order in which addresses are assigned to the interface. i have filed a FreeBSD PR for this issue: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296631 i will try updating the configuration on the BIRD router to assign addresses in the 'approved' order and see if this resolves the original problem. thanks again to everyone who replied to my original post.
