Abstract
In one embodiment, a system includes a switching processor and switching logic integrated with and/or executable by the switching processor. The switching logic is configured to install a Multicast Control (MC) table on the switching processor, the MC table facilitating management of switching across a virtual local area network (VLAN) via the switching processor. The switching logic is also configured to install a multicast router flood entry on the MC table at least partially in response to detecting that at least one multicast router is communicatively coupled to a port of the system, and receive at least one multicast packet at the switching processor. Moreover, the switching logic is configured to send the at least one multicast packet to a received multicast packet destination at least partially in response to determining the received multicast packet destination based at least in part on the multicast router flood entry.
