Configuring the prune delay
Configuring a prune delay interval on an upstream router on a shared network segment can make the
upstream router not perform the prune action immediately after it receives the prune message from its
downstream router. Instead, the upstream router maintains the current forwarding state for a period of
time that the prune delay interval defines. In this period, if the upstream router receives a join message
from the downstream router, it cancels the prune action. Otherwise, it performs the prune action.
Follow these steps to configure the prune delay time:
