Configuring Ssm Mappings; Configuring Igmp Proxying - 3Com S7906E Configuration Manual

To do...
Enter system view
Enter interface view
Enable the IGMP SSM
mapping feature
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

By performing this configuration multiple times, you can map a multicast group to different multicast
sources.
Follow these steps to configure an IGMP SSM mapping:
To do...
Enter system view
Enter public instance or
VPN instance IGMP view
Configure an IGMP SSM
mapping
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
details about the igmp-snooping host-join command, refer to IGMP Snooping Commands in the IP
Multicast Volume.
