WebIf the throughput of Join/Prune messages on the PIM neighbor is low, the neighbor may fail to process Join/Prune messages in a timely manner, causing route flapping. To prevent this problem, set a smaller queue size for periodically sending Join/Prune messages to … WebJoin messages are resent periodically so long a the receiver remains in the group. When all receivers on a leaf-network leave the group, the DR will send a PIM (*,G) Prune message towards the RP for that multicast group. However if the Prune message is not sent for any reason, the state will eventually time out.

RFC 4601: Protocol Independent Multicast - Sparse Mode (PIM-SM

WebA Protocol Independent Multicast (PIM) sparse-mode domain uses reverse-path forwarding (RPF) to create a path from a data source to the receiver requesting the data. When a receiver issues an explicit join request, an RPF check is triggered. A (*,G) PIM join message is sent toward the RP from the receiver's designated router (DR).
