Abstract

The present application provides a network traffic forwarding method, device, electronic equipment, and machine-readable storage medium. In this application, the local device receives the cross-protocol stack mapping entry for the target traffic sent by the user; wherein, the cross-protocol stack mapping entry includes at least the IP address of the local VTEP mapped from the first protocol stack The address mapping relationship to the second protocol stack; based on the cross-protocol stack mapping entry, the local device forwards the target traffic to the peer device, thereby providing a single-stack-only device accessing the EVPN system The VXLAN-based cross-protocol stack service communication enables flexible network deployment and reduces networking equipment costs.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a network traffic forwarding method, device, electronic equipment, and machine-readable storage medium. Background technique [0002] VXLAN (Virtual Extensible LAN, Virtual Extensible Local Area Network), is a network virtualization technology that can establish a layer-2 Ethernet network tunnel on the basis of a layer-3 network based on an IP network and adopts the "MAC in UDP" encapsulation form, thereby Realize cross-region Layer 2 interconnection. [0003] VXLAN technology creates a large number of virtual scalable local area networks on the existing network by establishing VXLAN tunnels. Different virtual scalable local area networks are identified by VNI (VXLAN Network Identifier, virtual scalable LAN network identifier). As we all know, due to the limited number of VLAN headers, only 12 bits, the limited number of VLANs is 2^12=4096, which cannot meet...
