Abstract
In one embodiment, a system includes a switching processor, logic configured for installing a Multicast Control (MC) table on a switching processor managing switching on a virtual local area network, logic configured for determining if multicast flooding is disabled in the switching processor, logic configured for installing a drop entry in the MC table upon determining that multicast flooding is disabled in the switching processor, logic configured for detecting whether one or more multicast routers is connected to one or more ports coupled to the switching processor, logic configured for receiving at least one multicast packet, and logic configured for dropping the at least one multicast packet based on the drop entry when no multicast router is connected to any of the one or more ports coupled to the switching processor. Other systems, methods, and computer program products are presented in accordance with more embodiments.
