Equipment upgrading method and device

Abstract

The application provides an equipment upgrading method and device. The method may include the following steps: when member equipment is primary equipment, finding a first forwarding entry associated with slave equipment to be upgraded in all local forwarding entries, and configuring the first forwarding entry to be forbidden from being used and deleted; receiving a synchronization request sent bythe slave equipment after the upgrade is completed, eliminating the configuration that the first forwarding entry is forbidden from being used and deleted, and synchronizing the first forwarding entrythat eliminates the configuration and all other forwarding entries that are recorded locally to the slave equipment; and after all the forwarding entries that are recorded locally are successfully synchronized to the slave equipment, switching the local equipment from the primary equipment to the slave equipment, and carrying out upgrading. By adopting the method provided by the application, theupgrade time for upgrading the equipment in an IRF cannot be increased, and the time of traffic interruption can also be reduced.

Description

technical field [0001] The present application relates to the field of computer communication, in particular to an equipment upgrading method and device. Background technique [0002] The core idea of ​​IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) is to connect multiple devices together through stacking links, perform necessary configurations, and virtualize them into one virtual device. Using this virtualization technology can integrate the hardware resources and software processing capabilities of multiple devices to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices. [0003] In the IRF, equal-cost multipath load sharing is usually formed for the master and slave devices in the IRF. During a slave upgrade, the forwarding path is switched to the master. After the upgrade of the slave device is completed, the slave device needs to wait for a set period of time. Within a set period of time after the u...

[0004] However, the above-mentioned setting time is usually set manually. When the above-mentioned setting time is set too short, the master device has not learned all new routes, and has not synchronized all new route generation forwarding entries to the slave device. , the roles of the master and slave devices are switched, so that the original slave device after the switch does not receive all the forwarding table entries corresponding to the interface of the slave device, and at the same time, the original master device after the switch is upgrading, resulting in some traffic paths , causing a cut-off

And when the above setting time is set too long, it will cause the entire upgrade time to become longer
