    3. 配置命令
      1. 配置 RIPv2 协议
      2. 把交换机接口变为三层接口,然后就可以配置 IP 地址。(本实验要把交换机当路由器用)
      3. 为环回接口配置 IP 地址。环回接口是路由器内部的软接口,除非路由器失效,否则,环回接口一直有效
      4. 取消自动汇总
      5. 配置水平分割
      6. 显示调试信息
    4. 实验任务

           R1(config-router)# network 192.168.3.0
    

    把交换机接口变为三层接口,然后就可以配置 IP 地址。(本实验要把交换机当路由器用)

    1E、拔掉 Router2 的 F0/1 的线后显示 Router1 的路由表

    图片描述

    配置 RIPv2(连续子网)。把两台交换机当成路由器使用,并配置三层接口。如下图所示,把 192.168.1.0/24 划分成四个子网(子网 1~子网 4),并和 192.168.2.0/24、192.168.3.0/24 一起配置成七个网络,见下图。路由器和交换机均设置为自动汇总(默认)。请先在下图标注网络号、接口名和接口 IP 地址(keyi 利用已有的输入位置.),然后进行配置

    接上一步,调整配为下图的非连续子网,标注网络号、接口名和接口 IP 地址。路由器和交换机均设置为自动汇总(默认)

    3A、PC1 pingPC2 和 PC3 后截屏

    图片描述

    3B、PC1 依次 ping 到 PC3 的路径上的 IP 地址后截屏

    见 3A 中的图,截在一起了。

    3C、Router1 的路由表

    图片描述

    3D、Router2 的路由表

    图片描述

    3E、Switch1 的路由表

    图片描述

    3F、Switch2 的路由表

    图片描述

    3G、把 Router1、Router2、Switch1、Switch2 的 Running-Config 分别保存到文件 s3.txt

    实验分析

    通过分析步骤[3]的路由表,解释[3B]某些 IP 的 ping 不通的原因

    PingPC2 可以 ping 通,pingPC3 不通,经检查,到 PC3 路径上第一个 ping 不通的 ip 是 192.168.2.1。原因是,Router2 路由表中,没有子网 1~4 的项(在不连续子网的网络边界,路由汇总会引起路由协议的丢失),ping 子网 3 的消息没有办法到达。

    把步骤[4B]和步骤[3B]所得结果进行对比,并进行解释

    这一步中,PC1 到 PC3 路径上每一个地址都可以 ping 通了。原因是,Router2 关闭自动汇总之后不再收集,因此其路由表中的项没有丢失,就可以 ping 通。

    分析在步骤[5G]和[5H]的两种情况下 RIP Update 分组差异

    在 5G->5H 后,GibgabitEthernet 0/6 分组下增加了很多项,而这些项也可以在上一个分组里找到。原因是取消水平分割之后,从本节点发送出去的那些路由又被发送了回来。

    实验体会

    本次实验中,我们在多种情况下配置了 RIPv2 协议,并探究了自动汇总、水平分割等多种 RIP 协议的技术的实际效果。在实验的最后,我们还自行探究了毒性反转技术避免计数到无穷问题的实际效果。总之,本次实验帮助我较好地理解了 RIP 协议的实际效果,还是很有意义的。
