When flood-unknown is enabled and IP multicast switching is enabled, multicast packets are flooded
on the VLAN until the multicast group membership table is updated. They are then forwarded based on
the multicast group membership table.
•
When flood-unknown is enabled and IP multicast switching is disabled, all multicast traffic will be
flooded on the VLAN.
•
When flood-unknown is disabled and IP multicast switching is enabled, multicast packets are not
flooded on the VLAN but will be forwarded once the multicast group membership table is updated.
•
If IP multicast switching is disabled and flood-unknown is disabled, all multicast packets are flooded
on the VLAN.
