New to this MC video stuff.

trying to setup a MC stream to go to two different locations. At the head end I have a device the generates the MC video from there it goes into a cisco 3750 port 24. Port 1 goes to one remote site same subnet and is working at the site. It then gets put out over the air and picked up at that site and turned around on a different MC. To be picked up at the headend. this is not working unless I turn off igmp snooping. Port 13 is going to the second site and I can not get the MC to show up. Its all switchs and no router.

basic drawing. port 1 and 13 get sent to a nid that is only a fiber transport to the sites.

MC Video source ----- Cisco 3750 ------- SG 300 site 1 ---- IP rec mux --- transmitter
227.1.1.50 |---------------- SG 300 site 2 ---- IP rec mux --- transmitter

site 1 sends back MC 227.1.1.150 to a device on port 5 on the 3750
site 2 sends back MC 227.1.1.100 to a device on port 17 on the 3750

I think I botched the 3750 config pretty good....

headend and site one are 10.10.4.x network site two is 10.10.6.x

Even among semi-experts, multicast is still a black art. I suspect that's why you aren't getting many responses. It's hard to determine multicast issues and functionality from a config. Even the TAC would need to use debugs and show commands during the multicast attempts.

On your routed G2/0/13 interface, have you tried removing the ip pim sparse-dense-mode command put in ip igmp snooping querier instead? Will it take it?
