初始配置
第一步：在R1上根据拓朴进行初始配置
R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.0
R1(config-if)#int s1/2
R1(config-if)#ip add 10.1.1.1 255.255.255.0

R1(config-if)#ip add 10.1.2.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#
第二步：在R2上根据拓朴进行初始配置
R2(config)#
R2(config)#
R2(config)#int lo1
R2(config-if)#ip add 172.16.1.2 255.255.255.0
R2(config-if)#int s2/1

R2#ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!! （表明直连正常）
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/14/36 ms

第三步：在R3上根据拓朴进行初始配置
R3(config)#
R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.0
R3(config-if)#int lo1

R3(config-if)#ip add 10.1.2.3 255.255.255.0
R3(config-if)#no sh
R3#
R3#ping 10.1.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.2.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
R3#
R3#
R3#
R3#ping 10.1.2.1
Type escape s
实验过程：
第一步：配置RIP协议
R1(config)#router rip
R1(config-router)#network 1.0.0.0
R1(config-router)#network 10.0.0.0
R1(config-router)#
R2(config)#router rip
R2(config-router)#network 127.16.0.0
R2(config-router)#network 2.0.0.0
R2(config-router)#network 10.0.0.0
R3(config)#router rip
R3(config-router)#network 3.0.0.0
R3(config-router)#network 192.168.1.0
R3(config-router)#network 10.0.0.0
第二步：检查RIP协议的运行情况
R1#sh ip pro
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 1 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for all interfaces is
Incoming update filter list for all interfaces is
Redistributing: rip
Default version control: send version 1, receive any version
Interface Send Recv Key-chain
Serial1/2 1 1 2
Serial1/3 1 1 2
Loopback0 1 1 2 （默认收V1和V2 发V1）
Routing for Networks:
1.0.0.0
10.0.0.0
Routing Information Sources:
Gateway Distance Last Update
10.1.2.3 120 00:00:19
Distance: (default is 120)
R1#
第三步：查看RIP协议运行正常后的路由情况
R1#show ip rou
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

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, * - candidate default
U - per-user static route, o - ODR
T - traffic engineered route
Gateway of last resort is not set
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Loopback0
R 3.0.0.0/8 [120/1] via 10.1.2.3, 00:00:14, Serial1/3
10.0.0.0/24 is subnetted, 2 subnets

R1#
第四步：我们在R1上进行rip调试
R1#

00:28:09: RIP: received v1 update from 10.1.2.3 on Serial1/3
00:28:09: 3.0.0.0 in 1 hops
00:28:09: 192.168.1.0 in 1 hops
第五步：我们在R2上进行rip调试

R 192.168.1.0/24 [120/2] via 10.1.1.1, 00:00:09, Serial2/1
R2#
第六步：分别查看R2和R3的路由表
