  本实验是对IPX的基本配置,并主要演示IPX在以太网上的各种封装类型。
  
  1.实验目的
  
  通过本实验,读者可以掌握以下技能
  ●启动IPX;
  ●配置IPX地址;
  ●在以太网上选择相应的封装;
  ●测试IPX网络的连通性;
  ●查看IPX相关信息。
  
  2. 设备需求
  
  本实验需要以下设备:
  ●路由器2台,命名为R1和R2,要求最少具有1个以太网接口,并且IOS软件为Desktop版本以上;
  ●1条交叉线序的双绞线,或2条正常线序双绞线和1个Hub;
  ●1台终端,如 2509路由器,及用于反向Telnet的相应电缆;
  ●1台带有超级终端程序的PC机,以及Console电缆及转接器。
  
  3.拓扑结构及配置说明
  
  本实验拓扑结构如图9.1所示,2台路由器通过以太网连接越来。
  IPX网络号为12。
  

  实验要求配置IPX地址,并实现R1和R2之间EPX上的连通性
  
  4. 实验配置及监测结果
  
  配置清单9-1记录了IPX的基本配置。

  (1)使用ipx routing命令启动路由器上的IPX路由能力,这个命令可以有1个参数,即IPX地址,如果不便用此参数,则路由器使用E0接口的MAC地址作为IPX地址,并在列配置清单时显示出来。
  (2)进入E0接口的配置模式下,输入命令ixp network 12,给E0所连接的网段分配IPX网络号为12。
  (3)对R2路由器做相同的配置。
  (4)show ipx interface e0命令列出了E0接口上的IPX地址和其他有关IPX的信息。这里的信息很多,我们光熟悉一下形式就可以了,在CCNA阶段不需要更深入的掌握。
  (5)ping ipx 12.0000.0c76.f736指令是ping路由器R1 E0接口本身,目的是测试上面的配置是否成功。
  (6)转到R2路由器上,使用ping ipx l2.0000.0c76.f736命令,则是测试从R2到R1通过IPX协议的连通性,测试是成功的,表明前面的配置完全正确。
  
  接下来我们来考察IPX协议在以太网上的封装类型。
  监测清单9-1记录了配置和监测的操作。
