UNREGISTERED MULTICAST PACKET FORWARDING TO MULTICAST ROUTER PORTS

摘要

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.

1. A system, comprising:
a switching processor communicatively coupled to at least one of:
a virtual local area network (VLAN) andone or more ports; and switching logic, the switching logic comprising:
logic configured to install a Multicast Control (MC) table on the switching processor, the MC table facilitating management of switching across the VLAN via the switching processor;logic configured to determine if multicast flooding is disabled in the switching processor;logic configured to detect whether one or more multicast routers are communicatively coupled to one or more of the port(s);logic configured to 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 one or more of the port(s);logic configured to receive at least one multicast packet at the switching processor;logic configured to determine at least one received multicast packet destination based at least in part on the multicast router flood entry; andlogic configured to send at least one received multicast packet to the at least one received multicast packet destination at least partially in response to determining the at least one received multicast packet destination.
