一、实验目的
通过本实验，可以掌握以下技能：
- 配置接口IP地址。
- 配置路由器主机名。
二、设备需求
- Cisco路由器1台，
- 1台带有超级终端程序的PC机，以及Console电缆及转接器。
三、拓扑结构及接口IP配置
1. 设置主机名、描述、IP地址和始终速率
- 进入特权模式，使用hostname命令来修改主机名，使用console线连接路由器和pc机
拓扑结构为：
拓扑结构1
- 使用banner命令来设置一个网络管理员可以看到的标志区。
拓扑结构和拓扑结构1一样。
- 使用ip address命令可以为一个接口添加IP地址。
拓扑结构如下：
拓扑结构2
接口及IP地址
- 使用description命令为一个接口添加标识
拓扑结构及实验结果如下：
拓扑结构3及实验结果
- 当模拟一个DCE的WAN链接时，可以为一个串行链路添加带宽和时钟速率
拓扑结构如下：
拓扑结构4

五、验证实验结果
- hostname修改成功
hostname Router-sjt
- 设置标志区
banner
- show interfaces FastEthernet 0/0后可以看到ip配置成功
show interfaces FastEthernet 0/0
- 可以看到接口的描述已经存在了
Description
- 使用ip为192.168.123.1的Router9去ping Router10，可以成功ping通
ping 192.168.123.2
六、实验总结
- 学会了使用pt模拟器
- 所有的配置操作都必须在特权模式下
- 对于路由器的接口需要按照实际情况来选择
- 如果能够相互ping通则说明配置成功，相互ping通会显示success和一堆!
- 连接线要看相应连接的装置和需要进行的操作，不然的话会出错
