I'm not sure what's wrong here, but ospfd and snmpd certainly work with
trunk ports (and also vlans on trunk ports).
$ ospfctl sh i trunk0

Did you create the trunk interface *before* or *after* starting ospfd?
I have seen ospfd get the wrong state on interfaces created after startup,
iirc sometimes "ifconfig down+up" helps, sometimes you need to restart
ospfd.
