Configuring the prune delay timer
An upstream router on a shared subnet can be configured with a prune delay interval. With this
configuration, the upstream router does not perform the prune action immediately after receiving 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 timer 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.

Configuring common IPv6 PIM timers
IPv6 PIM routers discover IPv6 PIM neighbors and maintain IPv6 PIM neighboring relationships with
other routers by periodically sending hello messages.
