Abstract

The invention provides a fault processing method and apparatus. The fault processing method includes the steps: when detecting that an AC (Attachment Circuit) link between a VTEP (VXLAN Tunnel End Point) and CE (Customer Edge) equipment is unavailable, determining an AC interface corresponding to the AC link and a VXLAN (Virtual eXtensible LAN) corresponding to the AC interface, and determining a corresponding MAC address according to the AC interface and the VXLAN; and sending a link fault message carrying the ID of the VXLAN and the MAC address to gateway equipment so as to enable the gateway equipment to determine the corresponding VXLAN tunnel according to the ID of the VXLAN and the MAC address, and stopping using the link between the gateway equipment corresponding to the VXLAN tunnel and the VTEP.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a fault handling method and device. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN technology. It uses BGP (Border Gateway Protocol, Border Gateway Protocol) on the control plane to advertise routing information, and uses VXLAN (Virtual eXtensible LAN) on the data plane. , scalable virtual local area network) encapsulation to forward user packets. When tenants' physical sites (Sites) are scattered in different locations, EVPN can provide Layer 2 interconnection for the same subnet of the same tenant based on the existing service provider or enterprise IP (Internet Protocol, Internet Protocol) network; Different subnets of the same tenant provide Layer 3 interconnection and provide Layer 3 interconnection with external networks. [0003] The basic EVPN networking architecture ma...
