making requests to join and leave multicast groups, or a multicast router sending
multicast packets to multicast group on the WAN side.
When a host wishes to join a multicast group, it sends IGMP REPORT message to the
device’s IGMP downstream interface. The proxy sets up a multicast route for the
interface and host requesting the video content. It then forwards the Join to the upstream
multicast router. The multicast IP traffic will then be forwarded to the requesting host. On
a leave, the proxy removes the route and then forwards the leave to the upstream
multicast router.
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: The interface that IGMP requests from hosts are sent to the
multicast router.
Downstream: The interface data from the multicast router are sent to hosts in
the multicast group database.
