原理
思科路由器得命令行模式操作和交换机的基本一样,在此就不一一赘述了
路由器提供广域网接口(serial高速同步串口),使用V.35线缆连接广域网接口链路。在广域网连接时一端为DCE(数据通信设备),一端为DTE(数据终端设备)。要求必须在DCE端配置时钟频率(clock
rate)才能保证链路的连通。
路由器端口的基础配置
进行serial端口0/1/0:Router(config)# interface serial 0/1/0
配置端口的IP地址:Router(config-if)# ip address IP 子网掩码
在DCE接口上配置时钟频率:Router(config-if)# clock rate 64000
开启该端口,使端口转发数据:Router(config-if)# no shutdown
注意
1、我用的模拟器是Cisco Packet Tracer Student,路由器在刚开始时是没有serial高速同步串口的,需要先添加
2、打开路由器的Physical(物理设备视图),关闭电源(点一下就行,不发绿光就成了)
3、选中你想添加的模块拖进去,然后打开电源就行了
4、添加成功
验证两台路由器之间的链路连通
1、网络拓扑图(右下角带有小时钟标识的是串口线DCE端,不带的是串口线DTE端,串口线DCE端先连哪个路由器哪个就是DCE端,DCE端的接口需配置时钟频率,端口配置完记得开启端口)
2、配置路由器A
3、配置路由器B
4、验证配置
