The client does not see IPTV. what's wrong? what else would you show?
With best regards, from Russia =)

I'm definitely not an expert with multicast, but offhand, I would say that you need to configure the RP address for ISP1's group to be ISP1's RP, and a different RP for ISP2's group.

If they just want IGMP from your device then you may just need to use IGMP proxy (no PIM), and set the group and upstream interfaces as static entries in the MFC tab.
