ip pim ssm
Use this command to configure Source Specific Multicast (SSM) and define the range of multicast IP addresses. The keyword default defines the SSM range as 232/8. To define an SSM range other than the default, specify an access-list.
When an SSM range of IP multicast addresses is defined with this command, the no (*,G) or (S,G,rpt) state is initiated for groups in the SSM range.
The messages corresponding to these states are not accepted and originate in the SSM range.
Use the no form of this command to disable the SSM range.
