 Stop bridge0 from forwarding packets.

 Remove the interface xl0 from the bridge bridge0.

+Flush all dynamically learned addresses from the address cache.

+Remove all addresses, including static addresses, from the address cache.

+.It Cm brconfig bridge0 -discover xl0
+The examples above mark the xl0 interface so that it will not learn
+addresses and adds a static entry for the host 8:0:20:1e:2f:2b on the xl0
+segment.
+Finally, xl0 is marked so that it will not receive packets with
+destinations not found in the address cache of bridge0.
+This setup is the most secure,
+and means that bogus MAC addresses seen by the xl0 side of the bridge
+will not be propogated to the rest of the network.
+Also, no packets will be sent on xl0 segment by the bridge unless they are
+broadcast packets or are for 8:0:20:1e:2f:2b.
