Enabling SSM mapping

Follow these steps to enable the IGMP SSM mapping feature:
To do...
Enter system view
Enter interface view
Enable the IGMP SSM
mapping feature
NOTE:
To ensure SSM service for all hosts on a subnet, regardless of the IGMP version running on the hosts,
enable IGMPv3 on the interface that forwards multicast traffic onto the subnet.

Configuring SSM mappings

You can map a multicast group to different multicast sources by performing this configuration repeatedly.
Follow these steps to configure an IGMP SSM mapping:
To do...
Enter system view
Enter public network IGMP
view or VPN instance IGMP
view
Configure an IGMP SSM
mapping
CAUTION:
If IGMPv3 is enabled on a VLAN interface, 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
more information about the igmp-snooping host-join command, see the
Reference
.

Configuring IGMP proxying

Configuration prerequisites

Before you configure the IGMP proxying feature, complete the following tasks:
