Victoir, You need to run either DVMRP or PIM-SM to route multicast traffic across VLANs. In the C3s this requires the Advanced Routing license which is an optional license sold separately from the switch. The Advanced Routing license enables OSPF, DVMRP, PIM-SM, and VRRP on the C3s. Please note that in a stack of C3s you will need a separate license for each switch else the stack will not form.
Good luck, Will _____________________________ William J.

The problem is that in our initial tests using just two C3 switches and one host attached to each, the multicast was only seen by both if the two were on the same VLAN. In this situation, one host would send out multicast and the other would listen. If we put the hosts on different VLANs the multicast was no longer seen (the listening host never hears the broadcast according to wireshark), despite the C3s being setup to send the multicast out the correct ports. Do the C3 switches lack the capability to route IGMP traffic between VLANs or am I missing some configuration step?
