一、实验拓扑 实验一PPP基本功能
实验步骤
1配置AR1的接口IP地址并配置PPP协议命令如下
Huaweisystem-view [Huawei]undo info-center enable [Huawei]sysname AR1 [AR1]interface s4/0/0 [AR1-Serial4/0/0]link-protocol ppp //将链路层协议封装为PPP [AR1-Serial4/0/0]ip address 10.0.12.1 24 [AR1-Serial4/0/0]quit 2配置全局地址池命令如下
[AR1]ip pool 1 //创建地址池编号为1 [AR1-ip-pool-1]network 10.0.12.0 mask 24 //设置地址和子网掩码 [AR1-ip-pool-1]gateway-list 10.0.12.1 //网关为10.0.12.1 [AR1-ip-pool-1]quit

[AR2]interface s4/0/0 [AR2-Serial4/0/0]ppp pap local-user huawei password cipher huawei
6在AR2设备上查看接口状态命令如下
AR2display interface Serial4/0/0 Serial4/0/0 current state : UP Line protocol current state : DOWN Description:HUAWEI, AR Series, Serial4/0/0 Interface Route Port,The Maximum Transmit Unit is 1500, Hold timer is 10(sec) Internet protocol processing : disabled Link layer protocol is PPP LCP stopped Last physical up time : 2024-09-18 19:38:19 UTC-08:00 Last physical down time : 2024-09-18 19:38:09 UTC-08:00 Current system time: 2024-09-18 19:41:44-08:00 Physical layer is synchronous, Virtualbaudrate is 64000 bps Interface is DTE, Cable type is V11, Clock mode is TC Last 300 seconds input rate 3 bytes/sec 24 bits/sec 0 packets/sec Last 300 seconds output rate 1 bytes/sec 8 bits/sec 0 packets/sec

总结:
PPP的配置实验通过模拟实际操作加深了对PPP协议工作原理、子网划分和静态路由配置的理解并验证了其在网络通信中的应用效果。以下是具体介绍
实验目的 掌握基本配置使学生掌握PPP帧的结构理解PPP帧格式中每个字段的含义并了解PPP协议中数据实际传送状况。理解工作机制通过实验学生能够理解PPP协议在点对点连接中的工作过程包括链路建立、身份验证和数据传输。实验步骤 创建实验拓扑使用华为eNSP软件或其他模拟器创建包含两台路由器的网络拓扑并配置同异步WAN接口卡。配置路由器接口为每台路由器的串口配置PPP协议设置IP地址并启用PAP或CHAP认证。验证网络连通性通过ping命令测试两台路由器之间的网络连通性确保PPP连接正常工作。实验结果 成功建立连接实验结果表明通过正确配置PPP协议和认证方式可以在两台路由器之间成功建立点对点连接。抓包分析使用Wireshark等抓包工具可以观察到PPP连接过程中的数据包交换情况进一步理解PPP协议的工作机制。实验总结 深化理解通过实验学生不仅掌握了PPP协议的基本配置方法还深入了解了其在不同场景下的应用如同步/异步专线、拨号链路等。实践能力提升实验过程中的操作练习提高了学生的动手能力和解决实际问题的能力为未来从事网络相关工作打下了坚实基础。
