We've got a lot of winXP boxes on-net which join the UPnP groups and the multicast routing table is filled with useless entries.
Given that we don't have access lists at layer2, what is the best way of preventing out routers: a. processing the IGMP joins b. forwarding the packets The network is 6500s running SXF6 (and upwards). If it matters (it shouldn't, I suspect) the networks are VRFs using MPLS and MVPN. I suspect a combination of "ip igmp access-list" and "ip multicast boundary" would help, but I'm not sure on the syntax. Also - is it *strictly* legal to limit these addresses to the local subnet? _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
