I don't know anything about bridges, but are you saying this is a configuration that used to work e.g. on FreeBSD 14 and now doesn't work after an upgrade?

Or something completely new you are trying on FreeBSD 15 and it is not doing what you expect?

It's quite difficult to diagnose what's going on in your system. I did notice in my system (which may have nothing to do with yours) that I need -stp when making changes to the bridge because it would bring my Cisco switch down for a little bit while running the spanning tree protocol.

Try this:

cloned_interfaces="bridge5"
ifconfig_re0="up"
ifconfig_bridge5="inet 10.8.1.200 netmask 255.255.255.0 addm re0 up"
defaultrouter="10.8.1.253"
