Prior to configuring Source-Specific Multicast (SSM) mapping, enable SSM mapping on the interface that connects the multicast device to the user network segment.
Before enabling SSM mapping, complete the following tasks:
Configuring a unicast routing protocol to interconnect the entire multicast domain.
SSM mapping must have been enabled before static SSM mapping policies are configured. The configured SSM source/group address mapping entries take effect only after SSM mapping is enabled on interfaces.
In the network segment where multicast services are provided in the SSM mode, certain hosts must run IGMPv1/v2 due to various limitations. To provide SSM services for the hosts, configure static SSM mapping on the FW.

To ensure that hosts that run any IGMP version on the network segment can obtain SSM services, configure IGMPv3 on the interface.
