摘要
VRRP协议使一组路由器组成一台虚拟路由器,局域网终端设备将访问外部网络的数据发送给虚拟路由器。而数据的实际转发则由VRRP备用组的活动路由器(Master)来完成,一旦Master出现故障,备用组中的备用路由器就按优先级选举产生新的Master接替故障设备承担的工作,利用VRRP协议定义的这种机制就能实现局域网络的路由冗余和负载均衡,保证局域网络运行的可靠性。
The VRRP protocol enables a group of routers constitute a virtual router,data transmission network terminal equip ment will access the external network to the virtual router.But the actual data forwarding by the active router VRRP standby group(Master) to complete,once the Master failure occurs,standby router backup in the group according to priority election of a new Master to replace faulty equipment to undertake the work,achieve routing redundancy and load balancing using local area network can be the mechanism of VRRP protocol definition,guarantee local network operation reliability.
