Context
An IPv6 PIM-SM network uses the SSM model to provide specified multicast services for user hosts. User hosts in a multicast group can receive multicast data sent from the specified multicast source to this group.
Pre-configuration Tasks
Before configuring IPv6 PIM-SM in the SSM model, configure an IPv6 unicast routing protocol to ensure that unicast routes on the network are reachable.
Configuration Procedure
Enabling IPv6 PIM-SM is a mandatory task. Configuring an SSM group policy is optional and can control the address range of SSM groups.
