本实验是对ipX协议的基本配置，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，读者可以把握以下技能
●启动IPX路由;
●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:
●Cisco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台终端服务器，如Cisco 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协议上的连通性
4. 实验配置及监测结果
配置清单9-1记录了IPX协议的基本配置。

(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，假如不便用此参数，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把握。
(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。
