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