摘要
利用 CISCO路由器的按需拨号路由功能 ,我们将普通电话线制作成专线的备份线路。文中对异步端口、拨号方式和按需拨号路由的配置进行详细说明 ,并给出了浮动静态路由、拨号后备两种按需拨号路由配置方案。使用该备份方法 ,在线路出故障时 ,可实现主从线路实时切换。
The common telephone line is changed to the backup line of special line using the function of Cisco router Dail-on-demand routing (DDR). Asynchronous port, dail mode and DDR configuration are described in detailed. The routing configuration of the floating static routing and dail backup are explained. The real time switching between primary line and second line could be performed automatically when the primary line is out of communication.
