Hi
I have a multi-VLAN network on which we are running live stats from a server (on VLAN6) out to a client (on VLAN2) using multicast. I am using Cisco 3560 switches to route ip traffic between VLANs but they are only running IPBase software so can not add mroute config into the VLAN. So I have enabled IGMP on all switches and a snooping querier on the main L3 3560 (as I believe this will allow routing between the VLANs). I am seeing all the snooping groups and can see the mcast IP addresses used by the systems but the traffic will not flow.
I can not ping the mcast IP Address and can not see anything joining the groups. Other mcast traffic is visible and I can see devices joined there but not on the specific group I am looking at. Here are the config specifics

I have a feeling I will have to put a new version of IOS on the switches to enable mrouting in the VLAN configuration but if anyone can advise then that would be greatly appreciated
