You are generally right. But it's pretty easy to turn a router into a bridge: bridge 1 protocol ieee interface ethernet 0 bridge-group 1 interface ethernet 1 bridge-group 1 Then you would want Spanning Tree Bridge Protocol Data Unit (BPDU) configuration and topology notification change frames to travel through the router as quickly as possible, so I can believe that they are put in Queue 0, if they need queuing. _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com > > Thanks, James.
