Usage
Information
By default, when you enable PIM-SM snooping, a switch floods all multicast traffic
to the PIM designated router (DR), including unnecessary multicast packets. To
minimize the traffic sent over the network to the designated router, you can disable
designated-router flooding.
When designated-router flooding is disabled, PIM-SM snooping only forwards the
multicast traffic, which belongs to a multicast group for which the switch receives
a join request, on the port connected towards the designated router.
