Hello messages are sent to neighboring PIM routers from which this device
has received probes, and are used to verify whether or not these neighbors
are still active members of the multicast tree.

The multicast interface that first receives a multicast stream from a
particular source forwards this traffic to all other PIM interfaces on the
router. If there are no requesting groups on that interface, the leaf node
sends a prune message upstream and enters a prune state for this
multicast stream. The prune state is maintained until the join-prune-
holdtime timer expires or a graft message is received for the forwarding
entry.
E
XAMPLE
Console(config-if)#ipv6 pim join-prune-holdtime 60
Console(config-if)#
This command causes this device to inform downstream routers of how
long it will wait before pruning a flow after receiving a prune request. Use
the no form to disable this feature.
