Just trying to understand a traffic pattern and my Google-fu is failing to turn up anything that covers this query.
Scenario: - 3750 stack with 2 members - 2 routers forwarding different multicast streams into the same VLAN The switch correctly shows both routers: #sh ip igmp snooping mrouter Vlan ports ---- ----- 4 Gi1/0/25(dynamic), Gi2/0/25(dynamic) The switch will take multicast traffic from router A and forward it to those ports where it has snooped an IGMP join. It also appears to forward the multicast out router B's port. Questions: Is this correct? Is multicast forwarded out all mrouter ports on the same VLAN except the ingress port? Is there a way to prevent this from happening? cheers Marty _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
