Configure a LAN interface as the Upstream Interface
This applies when the multicast server in on the LAN side. Hosts on the network can sent
IGMP request from the WAN side through the LAN interface. And the LAN interface, acting as
the upstream interface, forwards data multicast from the LAN-side multicast server to hosts
on the network.
In figure as shown below, there is a multicast router on the LAN side and LAN Group 1
interface is enabled as the upstream IGMP proxy. IGMP requests from the network are
forwarded to LAN group 1 and multicast frames from multicast router 1 are forwarded to hosts
on the LAN side (LAN group 3) and on the WAN side (DHCP1 and PPPoE1). Neither IGMP
request nor data multicast are forwarded to LAN Group 2.
