Method and apparatus for handling VRRP(Virtual Router Redundancy Protocol)-based network failure using real-time fault detection

摘要

The present invention relates to a method and device for a VRRP (Virtual Router Redundancy Protocol) backup router to track a network failure, receives an event message when a link state change occurs, analyzes information included in the event message, and analyzes the information Based on the above, the backup router is switched to the master router, and the event message includes the session state, and when the session state and the current session state included in the event message are different, a method of switching the backup router to the master router is disclosed. .
