VRRP-Virtual Router Redundancy Protocol, Hardware devices such as the gateway for the router to provide redundancy technology in the local area network's border. Makes the data in the LAN forwarding and other business units will not be a gateway device interrupted by a hardware failure, for the stability and non-LAN services to provide a guarantee of intermittent, and for users it is completely transparent.Relative to the cisco proprietary HSRP (Hot Standby Routing Protocol) and other terms of hardware redundancy protocol, VRRP protocol has less administrative overhead, configuration, deployment advantages of more simple, and VRRP can not change the current situation of network architecture implementation of the next upgrade, from the customer needs, the largest program on the saved money, but also have practical value.As if the knowledge of network routing technology framework,the paper firstly introduced the mainstream of network redundancy technologies and protocols, and proposed the existence of the significance of VRRP and VRRP protocol focuses on the data packet encapsulation format, and from the VRRP algorithm starting Analysis of the VRRP state machine, VRRP packets sent accepted way of switching mechanism standby gateway device, VRRP security and other issues. On this basis, then cited the cases to run the actual demonstration, detailed the specific steps given configuration.Finally, for this case appear in the VRRP stability and security issues and the progress has been optimized. VRRP protocol and the improved re-commissioning, operation, and ultimately passed the test showed that the improvement and optimization of protocols to solve the case after the basic problem.
