2. DDR（dial-on-demand routing）實例
此例通過Cisco 2500系列路由器的aux端口實現(xiàn)異步撥號DDR連接 。Router1撥號連接到Router2 。其中采用PPP/CHAP做安全認證，在Router1中應(yīng)建立一個用戶，以對端路由器主機名作為用戶名，即用戶名應(yīng)為Router2 。同時在Router2中應(yīng)建立一個用戶，以對端路由器主機名作為用戶名，即用戶名應(yīng)為Router1 。所建的這兩用戶的password必須相同 。
相關(guān)命令如下：
任務(wù) 命令
設(shè)置路由器與modem的接口指令 chat-script script-name EXPECT SEND EXPECT SEND (etc.)
設(shè)置端口在掛斷前的等待時間 dialer idle-timeout seconds
設(shè)置協(xié)議地址與電話號碼的映射 dialer map protocol next-hop-address [name hostname] [broadcast] [modem-scriptmodem-regexp] [system-script system-regexp] [dial-string]
設(shè)置電話號碼 dialer string dial-string
指定在特定線路下路由器默認 使用的chat-script script {dialerreset} script-name
