• Use the no form of this command to remove a static configuration of a SSM mode group mapping.

• The PIM Source-Specific Multicast (SSM) mode for the default SSM address range (232.0.0.0 through 

232.255.255.255) reserved by the Internet Assigned Numbers Authority is not enabled automatically 
and needs to be configured manually to support SSM. 

• You can also map additional multicast address ranges for the SSM group using this command. 

However, the multicast groups in the reserved address range can be mapped only to the SSM mode.

• If the group prefixes configured for two or more rows in this table overlap, the row with the greatest 

prefix length value is used for the overlapping range.

• Specifying the priority value obsoletes the override option.

• Note that once the priority option has been defined, a value of 65535 can be used to un-set the priority

-> ip pim ssm group 224.0.0.0/4 priority 50
