Once the table used to store multicast entries for IGMP snooping and
multicast routing is filled, no new entries are learned. If no router port is
configured in the attached VLAN, and unregistered-flooding is disabled,
any subsequent multicast traffic not found in the table is dropped,
otherwise it is flooded throughout the VLAN.
