Configuring the Prune Delay
If a downstream router on a multi-access LAN does not support the prune override interval option, you
can configure the prune delay time 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 a
period of prune delay time. In this period, if the upstream router receives a join message from the
downstream router, it cancels the prune action.
