Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
The accept-register command prevents unauthorized sources from registering with the rendezvous point. If an unauthorized source sends a register message to the rendezvous point, the rendezvous point immediately sends back a register-stop message.

Examples
The following example shows how to restrict the rendezvous point. Sources in the Source Specific Multicast (SSM) range of addresses are not allowed to register with the rendezvous point. These statements need to be configured only on the rendezvous point.
RP/0/RP0/CPU0:router(config)# router pim
RP/0/RP0/CPU0:router(config-pim-default-ipv4)# accept-register no-ssm-range
RP/0/RP0/CPU0:router(config-pim-default-ipv4)# exit
RP/0/RP0/CPU0:router(config)# ipv4 access-list no-ssm-range
RP/0/RP0/CPU0:router(config-ipv4-acl)# deny ipv4 any 232.0.0.0 0.255.255.255
RP/0/RP0/CPU0:router(config-ipv4-acl)# permit any
