Abstract
A system includes a switching processor and switching logic. The switching processor is communicatively coupled to a virtual local area network (VLAN) and/or one or more ports. The switching logic is configured to: install a Multicast Control (MC) table on the switching processor, determine if multicast flooding is disabled in the switching processor; detect whether multicast routers are communicatively coupled to the port(s); install a multicast router flood entry on the MC table at least partially in response to detecting that at least one of the multicast routers is communicatively coupled to the port(s); receive at least one multicast packet at the switching processor; determine at least one received multicast packet destination based at least in part on the multicast router flood entry; and send at least one received multicast packet to the destination(s). Exemplary computer program products and methods are also disclosed.
