Abstract

The invention provides a fault processing method and apparatus. The fault processing method and apparatus are characterized in that CE (Customer Edge) equipment in an EVPN (Ethernet Virtual Private Network) is connected with more than 2 VTEPs (VXLAN (Virtual eXtensible LAN) Tunnel End Point) in a distributed aggregation system; the more than 2 VTEPs respectively establish a neighborhood with gateway equipment; and the VTEPs are connected through an IPL (Intra Portal Link). The fault processing method is applied to any one VTEP of the more than two VTEPs, and includes the steps: receiving a data message sent from the gateway equipment; and after determining that the received data message is required to sent to the CE equipment through the IPL, sending a redirection message to the gateway equipment so as to enable the gateway equipment to send the data message which is required to sent to the CE equipment to the other VTEPs except the current 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...
