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

AoChengKaoRs(config-router)#

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 protocolsRouting Protocol is "rip"Sending updates every 30 seconds, next due in 3 secondsInvalid after 180 seconds, hold down 180, flushed after 240Outgoing update filter list for all interfaces is not setIncoming update filter list for all interfaces is not setRedistributing: ripDefault version control: send version 2, receive 2  Interface             Send  Recv  Triggered RIP  Key-chain  FastEthernet0/0       2     2       FastEthernet1/0       2     2     Automatic network summarization is in effectMaximum path: 4Routing for Networks:    192.168.10.0    192.168.12.0Passive Interface(s):Routing Information Sources:    Gateway         Distance      Last Update    192.168.10.1         120      00:00:01Distance: (default is 120)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 routeCodes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP       i - 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 - ODR       P - periodic downloaded static routeGateway of last resort is not setC    192.168.10.0/24 is directly connected, FastEthernet0/0R    192.168.11.0/24 [120/1] via 192.168.10.1, 00:00:07, FastEthernet0/0C    192.168.12.0/24 is directly connected, FastEthernet1/0R    192.168.15.0/24 [120/2] via 192.168.10.1, 00:00:07, FastEthernet0/0AoChengKaoRs#

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。
