Embodiment approach

[0038] As an implementation manner, when the fault notification information is transmitted in the form of protocol messages, that is, transmitted via BGP EVPN routing, the fault notification information is an EVPN route, and the EVPN route includes a fault status flag and a first source associated with the fault status flag Port1, EVPN routing information includes EVPN networking 20 information RD, link information EthernetSegment Identifier, broadcast domain Ethernet Tag ID, source IP address Source IP Addres, destination IP address destination IP Addres, fault status flags and fault status flags The associated first source port CRC errorbit.

[0039] When the fault notification information is an EVPN route, the first VTEP device 30 sends the EVPN route to the second VTEP device 40 through the second source port port2, so that the second VTEP device 40 will process the service traffic from the first to the second based on the fault status flag. A first destination port port1' as...

Abstract

The disclosure relates to the technical field of network communication, and provides a VXLAN (Virtual eXtensible Local Area Network) tunnel switching method and device. The VXLAN tunnel switching method and device are applied to first VTEP (VXLAN Tunnel End Point) equipment of an EVPN (Ethernet Virtual Private Network) networking, and the method comprises the steps of: when detecting that a firstsource port has a fault and a second source port is normal, switching service traffic to a second VXLAN tunnel corresponding to the second source port from a first VXLAN tunnel corresponding to the first source port; and sending fault annunciation information of the first source port to second VTEP equipment by the second source port, so that the second VTEP equipment processes the service traffic. According to the disclosure, when the current source port has the fault, transmission of the fault annunciation information is carried out by the detected VXLAN tunnels corresponding to other normalsource ports, so that reliable sending of the fault annunciation information and correct switching of a service traffic forwarding path can be ensured, and reliability of the EVPN networking is improved.

Description

Technical field [0001] The present disclosure relates to the field of network communication technology, and in particular, to a method and device for switching a VXLAN tunnel. Background technique [0002] EVPN (Ethernet Virtual Private Network) is a two-layer VPN (Virtual Private Network) technology. The control layer of EVPN uses MP-BGP (Multiprotocol Border Gateway Protocol) Announce EVPN routing information, and the data layer uses VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network) encapsulation to forward packets. [0003] The basic EVPN networking architecture mainly includes: VM (Virtual Machine, virtual machine), CE (CustomerEdge) equipment and VTEP (VXLAN Tunnel End Point, VXLAN tunnel end point) equipment. VXLAN is established between the physical ports of VTEP equipment For tunnels, physical ports may fail during packet forwarding, resulting in insufficient reliability of EVPN networking. Summary of the invention [0004] The purpose of t...
