5.2.6.4. IGMP Proxy
When “IGMP Proxy” (Internet Group Management Protocol Proxy) is enabled, the router can make intelligent multicast forwarding decisions by examining the contents of each frame’s IP header. Without the function, the router will broadcast the multicast packets to each port and may create excessive traffic on the network and degrade the performance of the network.
The IGMP Proxy page allows you to enable multicast on WAN and LAN interfaces. The LAN interface is always served as downstream IGMP proxy, and you can configure one of the available WAN interfaces as the upstream IGMP proxy. Upstream is the interface that IGMP requests from hosts are sent to the multicast router. Downstream is the interface data from the multicast router are sent to hosts in the multicast group database.
