      本節主要是通過靜態路由設置的實驗幫助讀者深入地體會路由的概念,并切實掌握靜態路由的設置、查看路由表、設置無類路由等常用的命令。
      
      1.實驗目的
      
      通過本實驗,讀者可以掌握以下技能:
      設置靜態路由

      設置啟用路由器的路由功能
      查看路由表
      ping和trace命令的使用
      
      2.設備需求
      
      3臺Cisco路由器,其中1臺具有2個以太網接口,其余2臺至少具有1個以太網接口;
      2臺Hub,4條雙絞線 (也可以用2條交叉網線直接把3臺路由器連接起來)
      1臺終端服務器,如cisco 2509路由器,及用于反向Telnet的相應線纜;
      1臺帶有超級終端程序的PC機,以及Console電纜及轉接器。
      
      3.拓撲結構及配置說明
      
      本實驗的拓撲結構如圖4-2所示。
      
    靜態路由的設置及相關命令

      3臺路由器分別命名為R1、R2和R3,所使用的接口和相應的IP地址分配如圖4.2中的標注。圖中的"/24"表示子網掩碼為24位,即255.255.255.0。
      實驗中,應使用靜態路由的設置。實現R2到R3在IP層的連通性,即要求從R2可以ping通R3,反之亦然。
      
      4.實驗配置及監測結果
      
      首先,根據拓撲結構圖的要求,正確配置各路由器的以太網接口。
      接下來的實驗記錄是從接口的配置工作完成之后開始的,具體內容見配置清單4-1。
      
      配置清單4-1配置和監測靜態路由
      
      第1段:測試基本的連通性
