What would you recommend for a multicast configuration on dual 6500's with Sup720's ? Each of the 720's have about 20 VLAN's/subnets. No routing protocol. All hosts point to the Sup720 as their default gateway and anything that is not connected to the 720 is default routed to a firewall.
I have a multicast source on one VLAN and a receiver can appear on any otherVLAN/subnet. I can get it working using PIM sparse or dense but do I really need this ? PIM seems the only way I can get the 720 to register the IGMP join from the destination and route the multicast traffic appropriately.
