Service Manual

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.
If the PIM DR flood is not disabled (default setting):
● Multicast traffic is transmitted on the egress port towards the PIM DR if the port is not the incoming
interface.
● Multicast traffic for an unknown group is sent on the port towards the PIM DR. When DR flooding is
disabled, multicast traffic for an unknown group is dropped.
