Configuring the Prune Delay
If a downstream router does not support the prune override interval field, you can configure a prune
delay interval on the upstream router so that it will not perform the prune action immediately after
receiving the prune message; instead, it maintains the current forwarding state for the prune delay
interval. In this period, if the upstream router receives a join message from the downstream router, it
cancels the prune action.
