Understood. But in our situation this VLAN is just a multicast traffic sink, it is not retransmitted. There are two routers because there are multiple sources of multicast traffic. > If both routers are talking PIM between them then only one of the them > would be the DR (Designated Router), and only this router would be > forwarding packets received on this LAN domain. We are using PIM neighbour filtering to prevent the routers associating because they are handling different multicast traffic. This is why my question focused on the 3750 stack. It seems that it's forwarding multicast out all mrouter ports except the ingress and I was wondering if there is a way to prevent this as router B never needs to see router A's multicast streams. 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/
