My network topology is like this:
WAN --- Router(NAT) --- L3 Switch --- IPTV Client
IPTV is based on mutlicast, so IPTV Client needs to join an IGMP multicast group on WAN. This is implemented with IGMP proxy on Router which is described here and here. However, the IGMP Proxy feature in a Cisco router seems to refers something else.
What is the equivalent IGMP proxy in Cisco routers?
