I have 2 devices on a spanned vlan on my WAN that require multicasting between them. Both devices are on the same vlan and connected to Cisco 6500 switch, but in different locations on my network. The switch has a L3 vlan configured for this interface, but with no PIM mode configured. The more I read about IGMP snooping as a possible solution, the more confused I become. Ideas anyone???
I have this problem too.
