Command Usage
◆
By default, the switch sends join/prune messages every 210 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
