you must enable multicast forwarding on the interface. For more information, see
multicast forwarding on a non-querier
To enable IGMP proxying:
Step
1.
Enter system view.
2.
Enable IP multicast routing
and enter MRIB view.
3.
Return to system view.
4.
Enter interface view.
5.
Enable IGMP proxying.
Enabling multicast forwarding on a non-querier interface
Typically, only IGMP queriers can forward multicast traffic and non-queriers cannot. This prevents
multicast data from being repeatedly forwarded. If a router interface on an IGMP proxy device failed
in the querier election, enable multicast forwarding on the interface to forward multicast data to
attached receiver hosts.
Configuration restrictions and guidelines
A shared-media network might have multiple MLD proxies, including one proxy acting as a querier.
To avoid duplicate multicast traffic, do not enable multicast forwarding on any of the non-querier MLD
proxies for the network.
Configuration procedure
To enable multicast forwarding on a non-querier interface:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Enable multicast forwarding on
the interface.
Configuring multicast load splitting on an IGMP proxy
This feature enables all proxy interfaces on an IGMP proxy device to share multicast traffic on a
per-group basis.
