Abstract

A heartbeat message transmission method, applied to a network including a virtual router and at least one third router respectively, the at least two routers communicate through VRRP; the first router in the virtual router is the main router, the At least one second router in the virtual router is a backup router, and the third router is reachable to the first router and the second router respectively. The method includes: generating a first VRRP heartbeat message, the first VRRP heartbeat message is used to indicate that the first router works normally; sending the first VRRP heartbeat message to the second router through the third router, and the first VRRP heartbeat message is used to indicate that the first router is working normally; The source IP address carried in a VRRP heartbeat message is the IP address of the first router, and the destination IP address is the IP address of the second router.

Description

technical field [0001] The invention relates to communication technology, in particular to a heartbeat message transmission method and device. Background technique [0002] With the rapid development of communication technology, Virtual Router Redundancy Protocol (hereinafter referred to as: VRRP) technology has also been developed. Through VRRP, a group of routers with gateway functions can be used as a virtual router to serve as a gateway between the terminal and the network. transfer data between. The VRRP election mechanism determines which router is the primary router to undertake the forwarding task. The primary router sends a VRRP heartbeat message to the backup router to inform the backup router that the primary router is in a normal state. When the primary router in the virtual router fails, the The backup router performs data forwarding operations as the main router. [0003] In the prior art, VRRP heartbeat messages are sent between the primary router and the ba...
