本节主要进行IPX RIP选择和服务方面的有关实验。
1.实验目的 通过本实验，读者可以掌握以下技能
●查看IPX路由表;
●配置IPX RIP;
●配置IPX服务;
●监测相关信息。
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9-2所示，2台路由器通过以太网连接起来。
以太网段上的IPX网络号为12，R1的L0接口上的IPX网络号为AA，R2的L0接口上的IPX网络号为BB。
4. 实验配置及监测结果 第1部分:IPX RIP路由的配置和监测 首先完成各有关接口的IPX配置。R1和R2路由器的配置见配置清常9-2。

(1)在R1和R2的配置中，按实验1的步骤启动IPX路由，并对L0、E0接口进行相应的配置即可。
(2)sh ipx route是查看IPX路由表的命令，其运行结果表明:从R1到R2的L0接口网段BB，存在1条路径，相对应的下一跳点是12.0000.0c8e.cdd2，即R2的E0接口，其路由类型是RIP。
我们在前面的配置中，从来没有配置任何IPX路由，路由器为什么能自动学习到不直接相连的IPX网段的路由信息呢?这是由于IPX RIP路由选择协议已经默认地在路由器上运行的缘故。
IPX RIP协议运行在两台路由器上，但列路由器运行配置时并不能看到有关它的配置，它是缺省的配置。不在配置清单中显示。如果关闭IPX RIP协议，列配置清单时可以看到no ipxrouter rip的配置语句。
(3)路由表项中的宇段意义:
R AA[O2/01]via 12.0000.0c760n36，3s，Et0
R:此路由项是由IPX RIP获取;
AA:目标网络号;
[02/01]:IPX RIP度量值，02是"tick"(滴答)数(1 tick约等于1/18秒)，01是跳数;
via:经由;
12.0000.0c760n36:下一跳地址;
3s:3秒，本条路由已存在的时间;
Et0:Ethernet0接口，是通往下一跳点的接口号。
