  • Method for operating a virtual router redundancy protocol router and communication system therefor
    Patent number: 8509059
    Abstract: A method for operating a VRRP router and a communication system therefor, wherein a first router operating as a backup router receives an advertisement message from a second router operating as a master router during a first period, and checks a session state of the second router using a BFD module during a second period that is shorter than the first period. Upon detecting a session down for the second router by the BFD module, the first router compares a time at which the advertisement message was received and a time at which the session down was detected, with the first and second periods, and determines an operation state of the second router according to comparison results. The first router switches from a backup router to a master router, and sends an advertisement message to the second router, if the second router is in a down state.
