Hello.
I've tried browsing the documentation, but it is vast and with my little knowledge of multicast world, hard to understand. Need to somehow pass multicast traffic to IPTV STB device on my LAN.
Here is a setup:
ISP PE (QinQ sub with ip pim sparse-mode) <-> Gi0/1.10 7206VXR Gi0/2.100 <-> 3750 <-> IPTV STB
Router is running IOS ver. 12.4(11)T.
When I check IGMP snooping groups on 3750, I see a group join from STB. How do I configure the router to pass this request to PE, so STB can get a stream?

Hello
"How do I configure the router to pass this request to PE,"
You have enabled pim sparse mode on the rtr correct? If so IGMP is also enabled which should allow MC traffic to traverse its igmp/pim interface.
What mode of pim-sparse are you using - Dont forget you will need a RP to be specified or you could try to use pim-sparse-dense mode.
sh ip igmp groups
sh ip igmp interface Gi0/1.10 / Gi0/2.100
sh ip pim inter Gi0/1.10 / Gi0/2.100
sh ip pim neigbour
sh ip pim rp mapping
sh ip mroute
