ME3600X igmp snooping problem

Hello,

I'm having problems with ME3600X running IOS 15.2(2)S2 (mandatory to support feature of multicast in VRF).

I have to disable IGMP snooping in order to get multicast working when a flow is going from a local vlan is routed toward two PIM vlans.If I have only 1 vlan in my outgoing interface list, it's working.

The show ip mroute seems to be correct but the multicast traffic is not forwarded until I disable igmp snooping on the vlan containing the source.

That's really a pain ! All my multicast traffic is flooded on all trunks containing the vlan of my multicast source...

If someone has a workaround for this !

Thanks ,

Christophe
