Follow these steps to configure an IGMP SSM mapping:
To do...
Enter system view
Enter IGMP view
Configure an IGMP SSM
mapping
If IGMPv3 is enabled on a VLAN interface of a switch that supports both IGMP Snooping and IGMP,
and if a port in that VLAN is configured as a simulated host, the simulated host will send IGMPv3 reports
even if you did not specify a multicast source when configuring simulated joining with the
igmp-snooping host-join command. In this case, the corresponding multicast group will not be
created based on the configured IGMP SSM mappings. For details about the igmp-snooping
host-join command, refer to IGMP Snooping Commands in the IP Multicast Volume.

Configuring IGMP Proxying

Configuration Prerequisites

Before configuring the IGMP proxying feature, complete the following tasks:
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
Enable IP multicast routing.

Enabling IGMP Proxying

You can enable IGMP proxying on the interface in the direction toward the root of the multicast
forwarding tree to make the device serve as an IGMP proxy.
Follow these steps to enable IGMP proxying:
To do...
Enter system view
Enter interface view
Enable the IGMP proxying
feature
Use the command...
system-view
igmp
ssm-mapping group-address
{ mask | mask-length }
