Description: vRtrPimNgImportJoinPrunePolicy4 is the fourth policy to be used for determining how the PIM Join-Prune messages are filtered. Join-Prune messages can be filtered based on different criteria such as multicast group or source address contained in the message, interface on which the messages are received or the address of the neighbor who is sending the message.

If multiple policy names are specified, the policies are evaluated in the order they are specified. The first policy that matches is applied.

The import policy name list, vRtrPimNgImportJoinPrunePolicy1 through vRtrPimNgImportJoinPrunePolicy5, 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.
