Problems solved by technology

[0006] In the existing EVPN, switching between Layer 2 VNI (L2 VNI) and Layer 3 VNI (L3 VNI) is not supported. To modify the L3 / L2 value of a VNI needs to completely delete the VNI and then reconfigure it. long, the network fluctuates greatly, and the disconnection time increases

Abstract

The invention discloses a routing processing method and device under an EVPN, and a medium. The method is applied to a first VTEP and comprises the steps that in response to a switching instruction ofswitching from a two-layer VNI to a three-layer VNI, related routing information of the two-layer VNI is deleted, and the switching instruction is issued by binding the two-layer VNI to a corresponding VRF; and after the switched three-layer VNI takes effect, full-amount routing update is carried out through interaction with a second VTEP, and the second VTEP is a BGP neighbor of the first VTEP.According to the invention, switching between the two-layer VNI and the three-layer VNI can be realized, configuration is simple, and the cost is low.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a routing processing method, equipment, and media under EVPN. Background technique [0002] Ethernet Virtual Private Network (Ethernet Virtual Private Network, EVPN) is a Layer 2 VPN technology. The control plane adopts Border Gateway Protocol (Border Gateway Protocol, BGP) to advertise EVPN routing information, and the data plane adopts Virtual eXtensible LAN (Virtual eXtensible). LAN, VXLAN) encapsulation to forward packets. EVPN can provide Layer 2 interconnection for the same subnet of the same tenant based on the existing service provider or enterprise IP network, and provide Layer 3 interconnection for different subnets of the same tenant through the EVPN gateway, and provide it with external networks Three layers of interconnection. [0003] EVPN usually adopts a core (represented by Spine)-branch (represented by Leaf) hierarchical structure, in whic...
