Just going by
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-bridging.html#AEN40035

did you start off with?

 # ifconfig bridge create

when your ifconfig -a should then also show:

  bridge0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
  (etc)

though it looks like 'cloned_interfaces=bridge0' is supposed to do that.
