Embodiment Construction

[0041] Aiming at the problem of poor suppression effect of VRRP oscillation existing in the prior art, the embodiment of the present invention provides a method for suppressing VRRP oscillation, which is applied to the backup equipment of the VRRP system. The flow of the method is as follows: figure 1 As shown, the execution steps are as follows:

[0042] S11: The process starts.

[0043] S12: Monitor whether the timeout timer has expired, if it is detected that the timeout timer has expired, execute S13; if it is detected that the timeout timer has not expired, execute S14.

[0044] The timeout timer can be used to monitor whether the period of not receiving VRRP heartbeat packets exceeds the timeout period.

[0045] S13: Switching to the master device of the VRRP system, sending VRRP heartbeat messages at a set period and updating the count of messages sent by the master device.

[0046] If it is detected that the timeout timer expires, it means that the VRRP heartbeat mes...

Abstract

The invention discloses a VRRP oscillation suppression method and device. The method comprises the steps that whether an overtime timer expires or not is monitored; if it is monitored that the timeouttimer expires, a main device of the VRRP system is switched to, the VRRP heartbeat message is sent in a set period, and a message sending count of the main device is updated; if it is monitored thatthe timeout timer does not expire, whether a VRRP heartbeat message is received or not when the current set period expires is determined, and if the VRRP heartbeat message is not received, the numberof messages which are not received by the standby equipment is updated; if the VRRP heartbeat message is received, the message receiving count of the standby device is updated, and the timeout duration is determined based on the message sending count of the main device, the unreceived message count of the standby device, the received message count of the standby device, the set period, the offsetduration and the set timeout multiple; and the timeout timer is reset based on the timeout duration and then the step of monitoring whether the timeout timer expires or not is executed. According to the scheme, the inhibition effect of VRRP oscillation can be improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for suppressing oscillation of a Virtual Router Redundancy Protocol (VRRP). Background technique [0002] VRRP is a routing fault-tolerant protocol, which can ensure that when the master device in the VRRP system fails, the backup device can switch to the master device without affecting internal and external data communication. [0003] Usually, the master device of the VRRP system will send VRRP heartbeat packets to the backup device at a set period. When the link between the master device and the backup device is unstable, for example, due to traffic attacks or other reasons, VRRP heartbeat packets will Intermittent packet loss, if the backup device does not receive the VRRP heartbeat message within the timeout period (the period set for the timeout multiple) and immediately receives the VRRP heartbeat message after switching to the master device, it ...
