Multicast Problem 1

[ATCal]

Environment in a large, flat VLAN (couple 6500s, L3 capable). One group recently introduced an application that delivers via multicast. Problem is, traffic is flooding to ALL ports,not just the multicast clients.
Need to know if the requirement is to segragate this server into another VLAN, or is there something in the switch that can handle this?

Thanks,

Separate VLAN, as the broadcasts won't be forwarded. That is the best way. Better than PIM.

Thanks.

I DO need to reach some clients on the main VLAN, so that would require the L3 in the switch to be multicast aware, correct? Any recommendation on what to run here?

Thanks!

Not necessarily---the easiest way I think is to put all servers and their prospective multicast clients in the same vlan, if it doesn't confuse administrative issues. It shouldn't since you have a flat LAN. If other things need to get to the clients in the multicast vlan, they still can via the backplane (routed), and can be separated via acls, but the multicasts will all remain in the same subnet.
