Abstract

The present invention provides a method and device for implementing centralized gateway networking, the method comprising: establishing an Ethernet virtual private network EVPN neighbor with the VTEP device with its own first type preset address; sending the next step to the VTEP device Jumping to the EVPN route of the second type preset address, and establishing a VXLAN tunnel with the VTEP device with the second type preset address; receiving the EVPN type 2 route sent by the VTEP device, the EVPN type 2 The route carries address resolution protocol (ARP) information of the virtual machine attached to the VTEP device, and stores the ARP information of the virtual machine. The application of the present invention can avoid the secondary Hash problem caused by simultaneous underlay and overlay load sharing.

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. VXLAN can provide Layer 2 interconnection for dispersed physical sites based on existing service provider or enterprise IP networks, and can provide business 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 a...
