Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] Embodiments of the present invention provide a message forwarding method and device, which are applied to the first edge device in an EVPN network, can prevent data loss when a link fails, and avoid network topology problems caused by link failure and failure recovery. of convergence.

[0031] It should be noted that, in this embodiment of the present invention, the EVPN network includes multiple edge devices, and there are established connections betw...

Abstract

Embodiments of the invention provide a method and a device for forwarding a message. The specific embodiment of the method comprises the following steps of selecting a first neighbor edge device as a second edge device when a first edge device detects that a first link has a fault, wherein the first neighbor edge device and the first edge device have a border gateway protocol (BGP) neighbor relation and are connected to a target virtual machine; obtaining a first logic channel between the first edge device and the second edge device; and when the first edge device receives a target message sent to the target virtual machine, forwarding the target message to the second edge device through the first logic channel in order to make the second edge device forward the target message to the target virtual machine. According to the embodiments, the data loss can be prevented when the link in an EVPN network has the fault, and the convergence of network topology, which is caused by the fault of the link and the fault recovery, is avoided.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] A multi-homing link refers to a link connection mode in which a virtual machine establishes a connection with two or more edge devices in an Ethernet Virtual Private Network (EVPN). [0003] The Ethernet virtual private network (EVPN) is a network built on a virtual extensible local area network (Virtual eXtensible Local Area Network, VXLAN). Virtual Extensible Local Area Network VXLAN is an overlay network technology, that is, a virtual network is constructed on the traditional network, and the traditional network does not need any adaptation. It uses the method of MAC in UDP to encapsulate the data, that is, the original message is encapsulated in the UDP message. The infrastructure of the VXLAN network includes an edge device (VXLAN Tunnel End Point, VTEP) of its core network and a user end device, ...
