IGMP SSM Mapping Settings
This window is used to view and configure the IGMP SSM mapping settings. The deployment of source
specific multicast (SSM) allows the network service provider to manage the IP multicast address easily.
When SSM is enabled, the last hop router will initiate to establish a source-based tree for the channel (S,
G) on receiving a (S, G) INCLUDE mode request that falls in the SSM range from the attached IGMPv3
hosts.
There are cases that the attached host is IGMPv1 or IGMPv2 hosts which only issue (*, G) requests. With
the SSM mapping, if the multicast group being requested that falls in the SSM range, the router is able to
map the (*, G) to a (S, G) requests based on the group address to source address mapping defined here.
The router will then issue to establish the source-based tree for the mapped (S, G). If multiple
associations exist, the router will issue to establish a (S, G) source-based tree for each S.
