On the network segment that provides SSM services, interfaces on multicast devices run IGMPv3. Due to various restrictions, some hosts must run IGMPv1 or IGMPv2. To provide SSM services for these hosts, IGMP SSM mapping needs to be configured on the multicast devices' interfaces connected to the user network segment. Enabling SSM mapping is a prerequisite for configuring static SSM mapping. If SSM mapping is not enabled on an interface, SSM source/group address mapping entries cannot take effect on the interface.
