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

Embodiments of the present invention provide a loop detection method, device, and readable storage medium, wherein the loop detection method is applied to a layer-2 virtual extensible local area network VXLAN network, including: through the spanning tree STP protocol, multiple leaf switches Any two leaf switches among the leaf switches send BPDUs constructed by each leaf switch to each other through the Layer 2 VXLAN tunnel, and record the tunnel identifier used to uniquely identify the Layer 2 VXLAN tunnel. STP protocol; elect a root switch and at least one non-root switch from multiple leaf switches; if the target switch in at least one non-root switch receives the BPDU message constructed by the root switch through the layer 2 VXLAN tunnel corresponding to the tunnel identifier, And when the target switch receives the BPDU message constructed by the root switch through the physical link, it is determined that a loop occurs on the Layer 2 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...
