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.
