HCIP---MGRE实验

news 2025/7/28 10:32:31

一、要求及拓扑

二、分析思路

IP 地址： 给所有路由器接口和 PC 分配 IP 地址，并规划隧道使用的 IP 地址段。
PPP/HDLC： 在指定的串行接口上配置相应的封装和认证（PAP/CHAP）。
GRE 隧道：
- 创建 R1-R4 的点对点 GRE 隧道，指定源/目的 IP 和隧道接口 IP。
- 创建 R1-R2 和 R1-R3 的 MGRE 隧道，R1 作为 Hub，为各端指定源/目的 IP 和隧道接口 IP。
RIP： 在所有路由器上启动 RIPv2，宣告所有连接的子网（包括物理接口和隧道接口）。

三、配置过程
