CISCO路由器配置命令详解
DDR(dial-on-demand routing)实例
此例通过Cisco 2500系列路由器的aux端口实现异步拨号DDR连接。Router1拨号连接到Router2。其中采用PPP/CHAP做安全认证,在 Router1中应建立一个用户,以对端路由器主机名作为用户名,即用户名应为Router2。同时在Router2中应建立一个用户,以对端路由器主机名作为用户名,即用户名应为Router1。所建的这两用户的password必须相同。
相关命令如下:
任务 命令
设置路由器与modem的接口指令 chat-s cript s cript-name EXPECT SEND EXPECT SEND (etc.)
设置端口在挂断前的等待时间 dialer idle-timeout seconds
设置协议地址与电话号码的映射 dialer map protocol next-hop-address [name hostname] [broadcast] [modem-s cript modem-regexp] [system-s cript system-regexp] [dial-string]
设置电话号码 dialer string dial-string
指定在特定线路下路由器默认 使用的chat-s cript s cript {dialer|reset} s cript-name
