Abstract

The invention provides an anti-attack method and device for an IRF system, wherein the method is applied to first equipment. The method comprises the following steps of: receiving an IRF Hello message sent by second equipment through a two-layer network; judging whether a MAC address of the second equipment carried in the IRF Hello message exists in a pre-stored MAC address table or not; and if not, determining that the second equipment is attack equipment, and abandoning the IRF Hello message. By means of the embodiment of the invention, the safety and the stability of the IRF system can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for realizing IRF system attack defense. Background technique [0002] IRF (Intelligent Resilient Framework, Intelligent Resilient Framework) is a software virtualization technology. Its core idea is to connect multiple devices together through IRF physical ports, and virtualize them into a "distributed device" after necessary configuration. 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] Generally, a "distributed device" composed of multiple devices through the IRF technology is called an IRF system, and each device in the IRF system is called a member device. refer to figure 1 , shows a schematic structural diagram of an existing IRF system, wher...
