When you're connected to a bridge, you exchange traffic with all other 
bridge users via unicast, so you should always see them and they should 
see you.  Whether you see multicast users depends on the state of 
multicast on the network where the bridge is running.  I suspect there 
was a problem with multicast here at Argonne at the time you had this
