Abstract

The invention provides a data forwarding method and device, network equipment and a computer readable storage medium, and relates to the technical field of virtual networks. The method is applied to an EVPN, and comprises the steps of obtaining to-be-forwarded routing service data in a first network layer, and determining that the to-be-forwarded routing service data is forwarded from the first network layer to the second network layer according to a destination address carried in the to-be-forwarded routing service data, wherein the first network layer and the second network layer are different types of network layers; acquiring forwarding interface information corresponding to the to-be-forwarded routing service data through the routing information of the second network layer, wherein the routing information of the second network layer is written according to a network interconversion instance, and the network interconversion instance comprises a first VPN instance identifier corresponding to the first network layer and a second VPN instance identifier corresponding to the second network layer; and forwarding the to-be-forwarded routing service data according to the forwarding interface information. According to the invention, mutual forwarding of routing service data between different types of network layers can be realized, and the reliability of communication is improved.

Description

technical field [0001] The present disclosure relates to the field of virtual network technology, and in particular, to a data forwarding method, device, network device, and computer-readable storage medium. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN technology. The control plane uses MP (backward compatibility)-BGP (Border Gateway Protocol, Border Gateway Protocol) to advertise EVPN routing information, and the data plane uses VXLAN (Virtual Extensible LAN, Virtual Extended Local Area Network) encapsulation to forward packets. When the physical sites of tenants 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) network; Different subnets provide Layer 3 interconnection and provide Layer 3 interconnection with external networks. [0003] EVPN usually adopt...
