AoChengKaoRs#config t
Enter configuration commands, one per line. End with CNTL/Z.
AoChengKaoRs(config)#router rip
AoChengKaoRs(config-router)#network 192.168.10.0
AoChengKaoRs(config-router)#network 192.168.12.0

验证实验结果
1. show ip protocols
该命令显示路由器的IP路由选择协议配置,详细说明了协议的配置情况以及协议之间的交互情况,还指出了下一次更新在何时进行
这种细节对诊断配置错误很有帮助,该命令如下:
AoChengKaoRs#sh ip protocols
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 3 seconds
Invalid after 180 seconds, hold down 180, flushed after 240

Incoming update filter list for all interfaces is not set

AoChengKaoRs#
同理可以验证另外2个路由器RIP协议(AoChengKaoRt,AoChengKaoRg)的配置情况。
2. show ip route
该命令显示路由器的IP路由选择表,详细指出了路由器是如何获悉网络和发现路由的
该命令如下:
AoChengKaoRs#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGPD - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter areaN1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGPi - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area* - candidate default, U - per-user static route, o - ODRP - periodic downloaded static routeGateway of last resort is not setC 192.168.10.0/24 is directly connected, FastEthernet0/0

C 192.168.12.0/24 is directly connected, FastEthernet1/0
R 192.168.15.0/24 [120/2] via 192.168.10.1, 00:00:07, FastEthernet0/0
AoChengKaoRs#
同理可以验证另外2个路由器路由表(AoChengKaoRt,AoChengKaoRg)的配置情况。
3. ping 指令的使用
1)从sa路由器去ping gill路由器,如果能ping通,说明RIP协议工作正常,如果不能ping通
所以有其他错误存在,需要检查硬件和其他配置。
2)从PC0( 192.168.12.2)ping PC1(192.168.15.2),检查是否可以ping通,如果不能ping通
所以有其他错误存在,需要检查硬件和其他配置。

实验总结
通过本次实验,我学会了如何配置配置接口IP地址以及如何配置RIPv2协议,并验证了RIPv2协议配置。
