Problems solved by technology

This method is only applicable to the case where a single server is connected to the routing device. For image 3 As shown, when the two servers are connected to the routing device at the same time, it is still unavoidable that there will be two master routing devices, and the probability of this problem will further increase with the complexity of the network structure, and the connection of the server cannot be guaranteed. input quality
[0007] It can be seen that when the local area network is connected to the external network using the VRRP protocol, when a link failure occurs and more than two master routing devices are generated, the existing technology cannot ensure that terminals such as servers in the local network can reliably access the external network.

Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Based on the VRRP protocol, among multiple VRRP routing devices, there is only one routing device as the master routing device (Master) to send data packets on behalf of the virtual routing device, and the others are backup routing devices (Backup); When layer failure (shutdown) event occurs, the VRRP routing device will turn to Initialize ...

Abstract

The invention provides VRRP access method, device and system, as well as a VRRP routing equipment. The VRRP access method comprises the following steps of: monitoring the communication of links among all servers in a local network by the VRRP routing equipment in a main control state; if the links are normal, transmitting a host router of the servers to the routing equipment in an external equipment; and if the links have failure, transmitting a first informing message for canceling the host router of the servers to the routing equipment in the external network. The VRRP access method, device and system, as well as the VRRP routing equipment, ensure the reliability when the servers are accessed into the external network on the basis of link communication and improve the access quality.

Description

technical field [0001] Embodiments of the present invention relate to network technologies, and in particular to a VRRP access method, device and system, and VRRP routing equipment. Background technique [0002] In a network based on Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol; TCP / IP for short), recovery and redundancy have become key features of today's local area network. Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol; abbreviated as: VRRP) is a protocol used to achieve router redundancy, which can be used for the default gateway (DefaultGateway) of terminal IP devices on a shared multi-access access medium (such as Ethernet). Make redundant backups. The VRRP protocol combines multiple routing devices running the VRRP protocol (referred to as VRRP routing devices) in the system to form a virtual routing device. This virtual routing device serves as the default gateway of the terminal device in t...
