H3C PPP认证试验报告(h3c网上学）

 

 

 

实验环境：两台H3C路由器，使用串行线缆相连；

实验目的：两台路由器之间实现PAP和CHAP认证，熟练掌握认证的配置；

实验步骤：

1. 根据实验拓扑合理的规划IP，并正确的对相应的接口配置IP地址；
   
2. 为了摸 拟PC,在两台路由器上分别启一个回环口，并进行IP地址的分配；
   
3. 使用RIPV2实现网络互连；且关闭自动汇总功能；
   
4. 在接口上查看默认封装的协议是HDLC还是PPP，只有PPP才支持认证；
   
5. 配置PAP明文认证（单向认证和双向认证）；
   
6. 配置CHAP密文认证（单向认证和双向认证）；
   

详细操作请见如下截图及相关文字说明：

在R1上面可以成功的PING通R2的回环口的地址

在R2 上面查看接口默认的封装协议是PPP

现将R2的S0/2/0接口的封装协议改为HDLC，发现接口DOWN掉，因此可以说明两极的封装必须一致
