Abstract

The invention provides a forwarding table updating method and device, and the method comprises the steps: enabling PE equipment to obtain an Ethernet segment identifier ESI and a media access controlMAC address carried in a message forwarded through an interface of the ESI identifier from at least one piece of opposite-end PE equipment; recording a corresponding relation among the VSI, the ESI and the outgoing interface information in a forwarding table based on the acquired ESI, the acquired MAC address, the virtual switching instance VSI corresponding to each MAC address and the outgoing interface information; if it is detected that the message forwarding path between the PE equipment and the opposite-end user edge CE device breaks down, adjusting outlet interface information corresponding to the ESI associated with the broken-down message forwarding path in the corresponding relation, wherein the opposite-end CE device is connected with the PE equipment through the at least one opposite-end PE equipment. Therefore, the forwarding table can be updated quickly, and quick switching of message forwarding paths is realized.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a method and device for updating a forwarding table. Background technique [0002] In the multi-homing networking based on the Ethernet Virtual Private Network (Ethernet Virtual Private Network, EVPN) virtual private LAN Service (VPLS), including the user edge (CustomEdge, CE) device and the service provider edge (Provider Edge, PE) equipment, each CE equipment can be connected to user equipment in the same site, such as mobile terminals, computers and other equipment. In order to realize intercommunication between user equipments in sites deployed in different geographical areas, CE equipment can be connected to different PE equipment through an Attachment Circuit (AC), and the PE equipment has at least one Virtual Switch Instance (Virtual Switch Instance, VSI ), through which each VSI can perform Layer 2 message forwarding, and by identifying the Media Acc...
