A method and device for vxlan VTEP adjacency learning

Abstract

The invention provides a virtual extensible local area network (VXLAN) tunnel end point (VTEP) adjacency learning method and a VXLAN VTEP adjacency learning device. The VXLAN comprises a VTEP server and a VTEP client. The VTEP serve stores VTEP adjacency information. The VXLAN VTEP adjacent learning method comprises the steps of when the VTEP server determines change of the stored VTEP adjacency information or verifies inconsistency between the VTEP adjacency information of the VTEP client and the VTEP adjacency information of the VTEP server, synchronizing the VTEP adjacency information stored in the VTEP server by the VTEP server to the VTEP client; and storing the VTEP adjacency information which is synchronized from the VTEP server by the VTEP client. Through the VXLAN VTEP adjacency learning method and the VXLAN VTEP adjacency learning device, quick learning for VTEP adjacency is realized through message interaction of two roles of the VTEP server and the VTEP client in a VXLAN network environment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for VXLAN VTEP adjacency learning. Background technique [0002] VXLAN (Virtual eXtensible Local Area Network, Virtual Extensible Local Area Network) is an Overlay (overlay) network technology built on an IP (Internet Protocol, Internet Protocol) network, which uses UDP (User Datagram Protocol, User Datagram Protocol) MAC (Media Access Control, Media Access Control) method is used for encapsulation, that is, ordinary Ethernet packets are encapsulated in UDP packets, so that ordinary Ethernet packets are transmitted as UDP data. [0003] VTEP (VXLAN Tunnel End Point, VXLAN tunnel end point), is the VXLAN tunnel endpoint, used for encapsulation and decapsulation of VXLAN packets. The VTEP is connected to the physical network and is assigned an IP address of the physical network, which is used for encapsulation and decapsulation of VXLAN packets. The source IP...

Problems solved by technology

[0014] However, on the one hand, during the VTEP adjacency learning process, the VXLAN end-user packets are sent to the VTEP learning unit. After the VTEP adjacency learning is completed, the packets are usually not forwarded, resulting in the loss of some end-user packets; On the other hand, this VTEP adjacency learning method is passive, untimely, inefficient and slow to converge

[0015] For the above technical problems, there is no good solution in the prior art
