Abstract

The invention provides a centralized gateway networking realization method and device. The method comprises the following steps: establishing an Ethernet virtual dedicated network EVPN neighbor with the VTEP equipment by using the own first type preset address; and sending an EVPN routing with the next hop of the second type preset address to the VTEP equipment, and establishing a VXLAN tunnel with the VTEP equipment by using the second type preset address; and receiving an EVPN 2-class routing sent by the VTEP equipment, wherein the EVPN 2-class routing carries an address resolution protocolARP information of a virtual machine mounted below the VTEP equipment, and saves the ARP information of the virtual machine. By applying the realization method provided by the invention, the secondaryHash problem caused by the coexistence of the Underlay and Overlay load burden can be avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for realizing centralized gateway networking. Background technique [0002] VXLAN (Virtual eXtensible Local Area Network, scalable virtual local area network) is based on IP (Internet Protocol, Internet Protocol) network, using "MAC (Media Access Control, Media Access Control) in UDP (User Datagram Protocol, User Datagram Protocol) "Layer 2 VPN (Virtual Private Network, Virtual Private Network) technology in encapsulation form. Based on the existing service provider or enterprise IP network, VXLAN can provide Layer 2 interconnection for dispersed physical sites and provide service isolation for different tenants. [0003] In practical applications, the centralized gateway of VXLAN is widely used. In the VXLAN centralized gateway network, there are multiple network devices as floating gateways. The Overlay (a stateless network technology) IP add...
