Below is PIM filter policy captured from concept guide.
Just wonder what's the format of rp_policy_name file? how to deny one specific multicast address?

 Filtering at RP

• When an encapsulated PIM register packet or PIM NULL register is received by the RP, and is denied

by the registering filter policy, the register message is discarded. Additionally, no (S,G) cache is

created in the PIM cache, and no register stop is sent to the FHR.

• The register drop counter is incremented, and the EMS message is logged.

• If a register is received from the MSDP, it also goes through the RP filtering policy.

The PIM filtering policy is configured at RP using the configure

 register-policy rp [rp_policy_name | none] command.
