Multicasting is useful when the same data needs to be sent to more than one device.
For instance, if one device is responsible for acquiring data that many other devices
need, then multicasting is a natural fit. Note that using multicasting as opposed to
sending the same data to individual devices uses less network bandwidth. The
multicast feature also enables you to receive multicast video streams from multicast
servers.
The IGMP Proxy page allows you to enable multicast on available WAN and LAN
connections. You can configure the WAN or LAN interface as one of the following:
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.
Ignore
No IGMP request nor data multicast are forwarded.
You can perform one of the two options:
1. Configure one or more WAN interface as the upstream interface.
2. Configure one or more LAN interface as the upstream interface.
To configure the IGMP Proxy:
1. Select
Advanced
.
2. Select
Application > IGMP Proxy
.
3. Configure the following interfaces:
Quickstart
LAN group 1
4. Click
Apply
to temporarily apply the settings.
5. To make changes permanent, click
