Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] The basic idea of ​​the VRRP packet transmission method provided by the present invention is: set the sending and receiving attribute for all interfaces on the network equipment, wherein, the attribute of the interface connected with the VRRP router on the network equipment is set to allow sending and receiving VRRP packets, and the network equipment The attributes of other interfaces are set to prohibit receiving VRRP packets; after the network device receives the VRRP packets from its own interface, it processes the received VRRP packets according to the set interface attributes.

[0035] Wherein, the network device may be another VRRP router connected to the VRRP router, or a forwarding device between two VRRP routers.

[0036] If the network ...

Abstract

The invention provides a virtual router redundancy protocol (VRRP) message transmitting method, comprising: setting transmit-receive attributes for all interfaces on network equipment, where the attributes of the interfaces on the network equipment, connected with VRRP router, are set into 'allow to transmit-receive VRRP messages', and those of the others are set into 'prohibit receiving VRRP messages'; after the network equipment receives VRRP messages from its own interfaces, it processes the received VRRP messages according to the set interface attributes. In addition, the invention provides a VRRP message transmitting device. And the invention can improve VRRP protocol safety, assure normal user data transmission, and avoid user flow interrupt and other abnormal conditions from occurring. Further, the invention can reduce network resources occupied by VRRP messages and improve the whole network performance.

Description

technical field [0001] The invention relates to data transmission control technology, in particular to a virtual router redundancy protocol (VRRP, Virtual Router Redundancy Protocol) message transmission method and device. Background technique [0002] With the increasing popularity of the Internet, people are increasingly dependent on the network, and at the same time, the demand for network reliability is also increasing. In the existing network system, in order to ensure the continuity and reliability of communication, the VRRP protocol is often used to realize the switch between the active and standby routers. The VRRP protocol ensures that when the next-hop router of the host fails, it can be replaced by another router in the backup state in time, so as to automatically restore the service as soon as possible. [0003] Figure 1 is a schematic diagram of a typical VRRP networking structure. The basic working principle of the VRRP protocol is described below in conjunct...
