Configuring IGMP SSM mapping
Due to some possible restrictions, some receiver hosts on an SSM network may run IGMPv1 or IGMPv2.
To provide SSM service support for these receiver hosts, you need to configure the IGMP mapping feature
on the last hop router.
Configuration prerequisites
Before configuring the IGMP SSM mapping feature, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Configure basic functions of IGMP.
