    摘要: In one embodiment, a method comprises assigning, by a distributed gateway protocol circuit in a first network switching device, a shared Media Access Control (MAC) address to a shared Internet Protocol (IP) address, the shared MAC address and the shared IP address enabling connected network devices to reach a distributed IP gateway in a network; and sending, by a layer 2 forwarding circuit in the first network switching device, an instruction via a peer data link to a peer layer 2 forwarding circuit in a second network switching device in response to the distributed gateway protocol circuit claiming active control of the distributed IP gateway, the instruction enabling the second network switching device to operate as part of the distributed IP gateway based on concurrent use of the shared MAC address and the shared IP address by the first network switching device and the second network switching device.
