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 present application discloses a route processing method, equipment and media under EVPN. The method is applied to the first VTEP, including: in response to a switching instruction from a Layer 2 VNI to a Layer 3 VNI, deleting the relevant routing information of the Layer 2 VNI, the switching instruction is issued by binding the Layer 2 VNI to the corresponding VRF ; After the switched Layer 3 VNI takes effect, the full route update is performed by interacting with the second VTEP, which is the BGP neighbor of the first VTEP. The present application can realize switching between a layer-2 VNI and a layer-3 VNI, and the 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...
