Description: vRtrPimNgImportRegisterPolicy4 is the the fourth policy to be used for determining how the PIM Register messages are filtered. Register policies are only relevant on the Rendezvous Point(RP). Register messages can be filtered based on different criteria such as multicast group or source address contained in the inner multicast data packet or the interface on which the Register Messages are received.

The import policy name list, vRtrPimNgImportRegisterPolicy1 through vRtrPimNgImportRegisterPolicy5, is handled by the SNMP agent as a single entity. When an SNMP SET request is received to modify one or more of the policy names, all the policy variables are first set to the empty string, ''H, and then the new names are set into the specified policy variables within a single SNMP SET PDU.
