Command Usage
• By default, the ECN330-switch sends join/prune messages every 60
seconds to inform other PIM-SM routers about clients who want to join
or leave a multicast group.
• Use the same join/prune message interval on all the PIM-SM routers in
the same PIM-SM domain, otherwise the routing protocol’s
performance will be adversely affected.
• The multicast interface that first receives a multicast stream from a
particular source forwards this traffic only to those interfaces on the
router that have requested to join this group. When there are no longer
any requesting groups on that interface, the leaf node sends a prune
message upstream and enters a prune state for this multicast stream.
The protocol maintains both the current join state and the pending RPT
prune state for this (source, group) pair until the jp-interval timer expires.
