Abstract

The present disclosure provides a method and device for updating a forwarding table. In the method, a PE device obtains the Ethernet segment identifier ESI and the media access control MAC carried in the message forwarded through the interface identified by the ESI from at least one peer PE device. address; based on the obtained ESI, MAC address, virtual switching instance VSI and outgoing interface information corresponding to each MAC address, record the corresponding relationship between VSI, ESI, and outgoing interface information in the forwarding table; if the PE device is detected When the message forwarding path between the edge CE device of the opposite end user fails, then adjust the outbound interface information corresponding to the ESI associated with the failed message forwarding path in the corresponding relationship; wherein, the opposite end CE device The PE devices are respectively connected through the at least one peer PE device. In this way, the forwarding table can be quickly updated to realize fast switching of message forwarding paths.

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...
