Thanks. We'll try just adding "ip igmp snooping querier" to the specific SVI to see if this in itself would be enough. Next up we try "ip pim sparse-mode" on the SVI and "ip multicast-routing" in global. I'll keep the list updated on how it went. :-) -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
