Abstract

The present application provides a message processing method and a gateway device. The method includes: the first gateway device receives the first one-arm BFD echo message returned by the network device through the first link, and the first one-arm BFD echo message The identification information is included, and the identification information is used to uniquely identify the second gateway device. The first gateway device determines to forward the first one-arm BFD echo message to the second gateway device according to the identification information. The first network device sends the first one-arm BFD echo packet to the second gateway device. The network device is multi-homing connected to the first gateway device and the second gateway device, the network device is connected to the first gateway device through the first link, the network device is connected to the second gateway device through the second link, and the first gateway device and the second gateway device The devices form an all-active gateway. The method provided in this application improves the efficiency of detecting whether a network device is normal by using a one-armed BFD ECHO session in a VXLAN multi-active gateway scenario.

Description

Technical field [0001] The present application relates to the field of communications, and more specific, involving a method and gateway device for packet processing. Background technique [0002] In the virtual extensible LAN, VXLAN) multi-live gateway scene, multiple gateway devices simulate a VXLAN tunnel endpoint by configuring the same virtual tunnel endpoint (VTEP) address to multiple gateway devices. . The gateway device can provide a gateway service whether the gateway service will provide a gateway service to the next hop device correctly. Single-arm two-way forwarding detection, BFD) packet detection mechanism is a single arm BFD echo (Echo) message to remote devices by local devices, remote devices return the arms BFD ECHO packet back to local A test mechanism for the device. The local device can detect the determination of whether the remote device has faults according to the single arm BFD ECHO message loopbacked by the remote device. In the VXLAN multi-live gateway ...
