【帧中继实验-ensp】

实验要求

在R1上开启一个点对点子接口，用于连接 R1–R2，两端IP地址为12.1.1.x 。开启一个多点子接口，用于连接R1–R3，R4，两段IP地址为134.1.1.x。

具体DLCI分配和映射关系如下：

R1 102 R2 201—动态映射
R1 103 R3 301—静态映射
R1 104 R4 401—静态映射
在R1、R3和R4上运行RIP协议。并在R1、R3和R4上的环回端口上配置IP地址，在R3和R4上用环回地址能够互相通信。（ping -a IP IP）

拓展：在R3和R4上用本地端口IP能进行互相通信。（ping）

实验拓扑

请添加图片描述

提示

设置子接口类型为点对点链路和点对多点链路命令：interface Serial 1/0/0.1 p2p/p2mp
子接口开启动态映射，没有学到映射关系，可以直接在子接口上设置DLCI ：fr map ip IP地址 DLCI
fr map ip IP地址 DLCI broadcast运行动态路由协议一定要敲，用于接受组播报文

详细配置

映射表
