Embodiment Construction

[0077] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0078] The present invention proposes a message sending method, which is applied to a system including a switch, a terminal, and a VRRP backup group. The VRRP backup group includes at least a Master device and a Backup device, wherein the terminal is connected to the switch, and the switch Connected with VRRP backup group, when the terminal needs to send data, it first sends the data to the switch, and the switch sends the data to the VRRP backup group according to the virtual MAC address of the VRRP backup group. For example, when the virtual MAC address is learned on the port of the Backup device, the switch sends the data to the Backup device in the VRRP backup group; when the virtual MAC address is learned on the port of the Master device, the switch sends the data to the VRRP backup group The Master device.

[0079] In the present invention, the Master device m...

Abstract

The invention discloses a message transmitting method and message transmitting equipment. The method comprises that: Backup equipment receives a first Advertisement message from Master equipment; and when determining it is necessary to transmit a second Advertisement message according to the priority of a VRRP backup operator of the Master equipment, the Backup equipment sends the second Advertisement message to an exchange board, and the exchange board learns the virtual MAC of the VRRP backup operator to a port connected with the Backup equipment according to a source MAC address of the second Advertisement message. In the invention, the constant flow rate of the VRRP backup operator in state switching is ensured.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message sending method and device. Background technique [0002] In practical applications, in order to realize the communication between the host and the external network, it is usually necessary to set a default route on the terminal, that is, the gateway set on the terminal, and its next hop points to a router, so that the communication between the terminal and the external network can be realized. Such as figure 1 A schematic diagram of a single-router network is shown. Wherein, when the Router (router) breaks down, all the terminals in the network segment that use the Router as the next hop of the default route will cut off the communication with the outside. [0003] In order to solve the above problems, VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) technology came into being, and this VRRP is applied on the third-layer swi...
