IGMP proxy
This feature provides support for multicast routing using IGMP (Internet Group Management
Protocol), which is typically required by the service controller. When enabled, IGMP:
Routes all multicast traffic received on the Upstream interface to the Downstream
interface.
Listens for IGMP host membership reports from authenticated users on the Downstream
interface and forwards them to the Upstream interface. IGMP host membership reports
from unauthenticated users are ignored.
Note An access list definition must be created to accept the multicast traffic (video streams,
etc.)
Due to the nature of multicast traffic, once a user registers for a stream it automatically
becomes visible to unauthenticated users as well. However, unauthenticated users are
not able to register with the IGMP group.
To view and configure IGMP proxy settings, select Service Controller >> Network >
IGMP proxy.
