AI Technical Summary

Problems solved by technology

The former cannot effectively limit the loop traffic, especially when the loop traffic and business traffic cannot be distinguished, and cannot effectively eliminate the loop; the latter, the loop elimination efficiency is low
[0004] It can be seen that the existing Layer 2 VXLAN network has the technical problem of low loop detection efficiency

Abstract

The embodiment of the invention provides a loop detection method and device and a readable storage medium, and the loop detection method is applied to a two-layer virtual extensible local area network(VXLAN), and comprises the steps: enabling any two leaf switches in a plurality of leaf switches to transmit BPDU messages constructed by the leaf switches through a two-layer VXLAN tunnel through aspanning tree (STP), recording a tunnel identifier for uniquely identifying a two-layer VXLAN tunnel, wherein each leaf switch in the plurality of leaf switches starts the STP protocol; selecting a root switch and at least one non-root switch from the plurality of leaf switches; and if a target switch in the at least one non-root switch receives the BPDU message constructed by the root switch through the two-layer VXLAN tunnel corresponding to the tunnel identifier, and the target switch receives the BPDU message constructed by the root switch through the physical link, determining that a loopoccurs in the two-layer VXLAN network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a loop detection method, device and readable storage medium. Background technique [0002] In the traditional data center network, a Layer 2 switch is connected to the server, and the Layer 2 switch is connected to the Layer 3 core switch. The gateways of the servers are all set on the core switch. Mutual visits are required. With the increase in the number of servers, the operation and maintenance difficulty and stability of the traditional two-tier data center network are facing difficulties. At present, the virtual extensible local area network (Virtual Extensible Local Area Network, VXLAN) networking method of the data center is often used. Specifically, , the link between the leaf switch leaf and the spine switch spine uses the IP protocol, and the network protocol is deployed to achieve intercommunication. At the same time, there is also a requirement for Lay...
