Abstract

The application provides a message forwarding method and device. The method comprises the following steps: a first interface board receiving a first VXLAN message carrying the first VNI, de-encapsulating the first VXLAN message to obtain the VLAN message, and adding the first VLAN identifier corresponding to the first VNI to the VLAN message to send to a switching network board; the switching network board acquiring the outlet interface corresponding to the VLAN message and the second VLAN identifier; replacing the first VLAN identifier in the VLAN message using the second VLAN identifier, and sending to a second interface board from the outlet interface; the second interface board using the second VNI corresponding to the second VLAN identifier to encapsulate the VLAN message to obtain a second VXLAN message, and forwarding the second VXLAN message to opposite-end distributed switching equipment. Through the combination of the interface of the distributed switching equipment and the switching network board, the VXLAN three-layer gateway is realized, and the message forwarding of each of the interface board and the switching network board is realized in a switching chip, and the forwarding efficiency is high.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a message forwarding method and device. Background technique [0002] Data centers usually use server virtualization technology to virtualize a physical server into multiple VMs (Virtual Machines, virtual machines), and require physical servers to support VXLAN (Virtual Extensible LAN, scalable virtual local area network) technology to send VMs The VLAN (Virtual Local Area Network, virtual local area network) message encapsulated into a VXLAN message, and then the switching device performs layer-3 forwarding. However, the switching chip in the general switching device does not support the VXLAN layer-3 gateway function. [0003] In the prior art, when the switching chip of the switching device that does not support the VXLAN layer-3 gateway receives the first VXLAN message, it usually sends the first VXLAN message to the processor, and the processor pr...
