Automatic promiscuous forwarding for a bridge

摘要

An example system to disable a promiscuous mode of a network interface includes a plurality of local network interfaces. Each local network interface of the plurality is coupled over a network to one or more remote network interfaces. Each remote network interface is assigned one or more remote network addresses, and the plurality includes a local network interface in a promiscuous mode. The system also includes a bridge module that determines whether a list of all remote network addresses that are coupled to a subset of local network interfaces is known. The subset includes the plurality of local network interfaces excluding the local network interface. When the list of all remote network addresses that are coupled to the subset is determined to be known, the bridge module disables the promiscuous mode of the local network interface and adds all remote network addresses that are coupled to the subset to a filtering table.

1. A system to disable a promiscuous mode of a network interface, the system comprising:
a plurality of local network interfaces, wherein each local network interface of the plurality is coupled over one or more networks to one or more remote network interfaces, and wherein each remote network interface is assigned one or more remote network addresses, and the plurality of local network interfaces includes a first local network interface in a promiscuous mode; a plurality of filtering tables stored in a memory, wherein each filtering table of the plurality of filtering tables is coupled to a local network interface of the plurality of local network interfaces; and a bridge module coupled to the plurality of local network interfaces, wherein the bridge module determines whether a list of all remote network addresses that are coupled to a subset of local network interfaces is known, wherein the subset includes the plurality of local network interfaces excluding the first local network interface, and wherein when the list of all remote network addresses that are coupled to the subset is determined to be known, the bridge module disables the promiscuous mode of the first local network interface and adds all of the remote network addresses that are coupled to the subset to a filtering table that is coupled to the first local network interface.
