一、 設置路由器治理信息 1、 用扁平控制線接上9孔接頭，連接CONSOLE到終端或PC串口，設置終端或直接連至串口的超級終端的參數：BAND率9600，無奇偶校驗，8位數據位，1位停止位. 2、 路由器上電，終端屏幕會顯示上電過程。 3、 進入特權模式設置口令 line vty 0 4 passWord bc123 exit enable secret bc123fzq123 exit 4、 在特權模式設置路由器信息： hostname bc3640 ip domain-list jzl.cq ip domain-list jz2.cq ip domain-name jzl.cq ip name-sever 10.54.34.1 5、 進入全局模式，配置以太網地址 configure timinal interface fastethernet 0/0 ip address 192.168.254.254 255.255.255.0 no shutdown exit interface fastethernet 1/0 ip address 10.154.34.253 255.255.255.252 noshut down exit 設置IP路由功能開放 ip routing 設置撥入客戶名和口令 username user1 password 123 設置撥號組參數，為撥號客戶指定ip地址 line 65 72 autoselect ppp modem inout transport inputall exit interface group-async1 ip unnumbered fastethernet 1/0 encapsulation ppp dialer in band dialer map ip 10.154.34.247 name user 1 async default routing anync mode interactive peer default ip address pool default ppp authentication chap pap group-ranger 65 72 ;路由器遠程撥入端口 設置內部ospf路由協議、靜態路由 access-list 77 permit 10.154.34.0 0.0.1.255 router ospf 110 redistribute connected subnets redistribute static subnets passive-interface fastethernet 0/0 network 10.154.34.0 0.0.255 area 0 network 10.154.35.0 0.0.0.255 area 0 distribute-list 77 out exit

二、 CISCO路由器廣域網配置向導 1、 dial-on demand routing (ddr)是用公共電話網提供了網絡連接。通常的，廣域網大多數使用專線連接的，路由器連接到類似MODEM OR ISDNTAS 的數據終端DCE設備上，他們支持同步V.25BITS協議，你可以用SCRIPTS AND DIALER命令設定撥號串。 DDR比較適用于用戶對數率要求不高，偶然有數據傳輸或只是在特定時候傳輸數據，比如銀行每晚傳送報表等等情況下。 當一個感愛好的包到達路由器時，產生一個DDR請求，路由器發送呼叫建立信息給指定的串口的DCE設備，這個呼叫就把本地的和遠程的設備連接起來，一旦沒有數據傳輸，空閑時間開始記時，超過設置的記時時間，連接終止。DDR現在都用靜態路由來傳輸數據，避免路由交換引起的DDR撥號。 和XNS可以通過DDR路由尋址，同步串口，異步串口和ISDN端口可以配置成到一個或多個目的地的DDR連接。 下面是一個典型的DDR連接： 在配置DDR過程中，我們可以把一個或幾個物理端口配置成一個邏輯撥號接口，他可以是同步V.25方式，同步DYR啟動撥號或異步CHATSCRIPT方式 在端口配置模式下： 在一個端口激活DIAL-ON-DEMAND ROUTING 命令：dialer in-band 指定一個端口為撥號訪問組：dialer-group group-number 指定一個單一電話號碼：dialer string dialer-string 斷線前空前等待時間：dialer idle-time seconds 定義一個或多個目的電話號碼表： dialer map PRotocol net-hop-address dialer-string 限定傳輸的access-list表或特定協議： dialer-list dialer-group list access-list-number或 dialer-list dialer-group protocol protocol name(permit/deny/list access-list-number) 具體配置： ！ interface serial 0 ip address 131.108.126.1 255.255.255.0 dialer in-band dialer-group 1 ! dialer map ip 131.108.126.2 55551234 ! dialer idle-timeout 300 dialer backup example A) 同步V.25bits方式 configuration for routerA: interface serial 10:0 backup delay 0 10 backup interface serial 110 ip address 16.217.30.2 255.255.255.252 ! interface serial 110 ip address 16.30.16.81 255.255.255.25.0 encapsulation ppp dialer in-band dialer string 8292 dialer-group 1 pulse-time 1 ! dilar-list 1 protocol ip permit B) 輔助口作撥號備份 configuration for routerA: chat-script mydial “””atdt 8292” timeout 60 “connect” ! interface serial 0 backup delay 0 0 backup interface async1 ip address 16.3.1.1 255.255.255.0 encapsulation ppp ! interface async1 ip address 16.3.2.1 255.255.255.0 encapsulation ppp keepalive 9 async default routing async dynamic address async dynamic routing async mode dedicated dialer string 8292 dialer-group 1 ! dialer-list 1 protocol ip permit ! line aux 0 script dialer mydial modeinout transport output none stopbits 1 flowcontrol hardware speed 9600 subinterface example (frame realay) configuration for routerA: interface serial 0 encapsulation frame-relay interface serial 0.1 multipoint ip address 11.10.11.1 255.255.255.0 frame-relay interface-dlci 41 frame-relay interface-dlci42
