摘要
随着Internet的快速发展,基于网络的应用越来越多,因此对网络的可靠性要求也越来越高。购买增加网络新设备是一种很好的解决方案,但从节约成本的角度考虑,采用较为廉价的冗余技术,可以在可靠性和经济性方面找到平衡点。VRRP是一种备份冗余解决方案。它共享多路访问介质(如以太网)上终端IP设备的默认网关进行冗余备份。当其中一台路由器设备出现故障时,备份路由器设备能够及时唤醒并完成转发任务,从而保持通信的连续性和可靠性。
With the rapid development of Internet,there are more and more network-based applications,raising the requirement of network reliability.It＇s a good solution to purchase new network devices,and in terms of cost savings,some low-cost redundancy technology can be applied to find a balance in reliability and economy.With the backup redundancy solution of VRRP,the default gateways of IP terminals on multiple access media（such as Ethernet） are shared to backup redundancy.The backup router will timely boot and complete the forwarding task when some router doesn＇t run properly,which guarantees the consistency and reliability of communication.
