I don't know much about multicast, but aren't routed multicast packets sent as L2 unicast between multicast routers? I'm just guessing here, but I don't see why routed multicast traffic would need to have the L2 group bit set. I that is the case then a switch in between two PIM interfaces shouldn't need to know anything about multicast. -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
