Implementation method of remote IRF stacking and equipment thereof

Abstract

The invention discloses an implementation method of remote IRF stacking and stacking equipment. The method is applied to first access equipment and second access equipment which need to establish IRF stacking, and the first access equipment is connected with the second access equipment by intermediate equipment. The method comprises the following steps: performing role election among access equipment crossing networks, and transmitting link information; sending a link configuration message to the access equipment of master equipment according to the election result to trigger the intermediate equipment and slave equipment among the access equipment to add a member port to a private VLAN; and establishing a layer-two tunnel, and performing data message interaction by virtue of the layer-two tunnel to realize the IRF stacking crossing networks among the access equipment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and equipment for realizing remote IRF (Intelligent Resilient Framework, intelligent resilient framework) stacking. Background technique [0002] IRF, also known as IRF stacking, is a technology that connects multiple devices through stacking ports to form a "virtual logical device". The user manages this "virtual logical device" to manage all devices in the stack. [0003] A schematic diagram of a group of IRF stacked networks is as follows: figure 1 shown. A single device in an IRF stack is called a member device. According to different functions, member devices are divided into two roles: master device and slave device. The master device is responsible for managing the entire stack. Only one member device in a stack can become the master device at a time. The Slave device belongs to the Master device and operates as the backup device of the M...

AI Technical Summary

Problems solved by technology

The reason is that if the intermediate device is located between the stacking devices, once the non-stacking-related packets of the intermediate device enter the stacking port of the stacking device, the stacking device cannot process these non-stacking-related packets, thus affecting the normal operation of the stacking device. use

This limits the networking application of stacking to a certain extent
