一、 设置路由器治理信息 1、 用扁平控制线接上9孔接头，连接CONSOLE到终端或PC串口，设置终端或直接连至串口的超级终端的参数：BAND率9600，无奇偶校验，8位数据位，1位停止位. 2、 路由器上电，终端屏幕会显示上电过程。 3、 进入特权模式设置口令 line vty 0 4 passWord bc123 exit enable secret bc123fzq123 exit 4、 在特权模式设置路由器信息： 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、 进入全局模式，配置以太网地址 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 设置IP路由功能开放 ip routing 设置拨入客户名和口令 username user1 password 123 设置拨号组参数，为拨号客户指定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 ;路由器远程拨入端口 设置内部ospf路由协议、静态路由 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路由器广域网配置向导 1、 dial-on demand routing (ddr)是用公共电话网提供了网络连接。通常的，广域网大多数使用专线连接的，路由器连接到类似MODEM OR ISDNTAS 的数据终端DCE设备上，他们支持同步V.25BITS协议，你可以用SCRIPTS AND DIALER命令设定拨号串。 DDR比较适用于用户对数率要求不高，偶然有数据传输或只是在特定时候传输数据，比如银行每晚传送报表等等情况下。 当一个感爱好的包到达路由器时，产生一个DDR请求，路由器发送呼叫建立信息给指定的串口的DCE设备，这个呼叫就把本地的和远程的设备连接起来，一旦没有数据传输，空闲时间开始记时，超过设置的记时时间，连接终止。DDR现在都用静态路由来传输数据，避免路由交换引起的DDR拨号。 和XNS可以通过DDR路由寻址，同步串口，异步串口和ISDN端口可以配置成到一个或多个目的地的DDR连接。 下面是一个典型的DDR连接： 在配置DDR过程中，我们可以把一个或几个物理端口配置成一个逻辑拨号接口，他可以是同步V.25方式，同步DYR启动拨号或异步CHATSCRIPT方式 在端口配置模式下： 在一个端口激活DIAL-ON-DEMAND ROUTING 命令：dialer in-band 指定一个端口为拨号访问组：dialer-group group-number 指定一个单一电话号码：dialer string dialer-string 断线前空前等待时间：dialer idle-time seconds 定义一个或多个目的电话号码表： dialer map PRotocol net-hop-address dialer-string 限定传输的access-list表或特定协议： dialer-list dialer-group list access-list-number或 dialer-list dialer-group protocol protocol name(permit/deny/list access-list-number) 具体配置： ！ 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) 辅助口作拨号备份 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
