RIP、IGRP
实验拓扑：
实验环境：
本次实验环境使用的是DynamipsGUI模拟软件进行的实验，实验拓扑中的路由器型号为思科c3620系列，路由器之间使用广域网线进行连接
实验配置：
R1配置：
R1(config)#int f0/0
R1(config-if)#ip add 192.168.1.1 255.255.255.0
R1(config-if)#no shutdown
R1(config)#int s1/0
R1(config-if)#ip add 192.168.4.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#int s1/1
R1(config-if)#ip add 192.168.5.1 255.255.255.0
R1(config-if)#no shutdown
R1#show ip route
Gateway of last resort is not set

R2(config)#router rip
R2(config-router)#network 192.168.2.0
R2(config-router)#network 192.168.4.0
R3配置
R3(config)#int f0/0
R3(config-if)#ip add 192.168.3.1 255.255.255.0
R3(config-if)#no sh
R3(config-if)#no shutdown
R3(config-if)#int s1/1
R3(config-if)#ip add 192.168.5.2 255.255.255.0
R3(config-if)#no shutdown
R3#sh ip route
Gateway of last resort is not set
C 192.168.5.0/24 is directly connected, Serial1/1
C 192.168.3.0/24 is directly connected, FastEthernet0/0
R3(config)#router igrp 100
R3(config-router)#net
R3(config-router)#network 192.168.3.0
R3(config-router)#network 192.168.5.0
R3#sh ip route
Gateway of last resort is not set
I 192.168.4.0/24 [100/10476] via 192.168.5.1, 00:00:14, Serial1/1
C 192.168.5.0/24 is directly connected, Serial1/1
I 192.168.1.0/24 [100/8486] via 192.168.5.1, 00:00:14, Serial1/1
C 192.168.3.0/24 is directly connected, FastEthernet0/0
R2#sh ip route
Gateway of last resort is not set
C 192.168.4.0/24 is directly connected, Serial1/0
R 192.168.5.0/24 [120/1] via 192.168.4.1, 00:00:14, Serial1/0
R 192.168.1.0/24 [120/1] via 192.168.4.1, 00:00:14, Serial1/0
C 192.168.2.0/24 is directly connected, FastEthernet0/0
R1#sh ip route
Gateway of last resort is not set
C 192.168.4.0/24 is directly connected, Serial1/0
C 192.168.5.0/24 is directly connected, Serial1/1
C 192.168.1.0/24 is directly connected, FastEthernet0/0
R 192.168.2.0/24 [120/1] via 192.168.4.2, 00:00:00, Serial1/0
I 192.168.3.0/24 [100/8486] via 192.168.5.2, 00:00:58, Serial1/1
发现R2和R3 没有发现对方的路由信息，这主要是因为rip和igrp是两种不同的协议，要想让他们学习到彼此之间的路由，就得使用重分布命令将rip和igrp的路由重分布到彼此的路由协议中
在R1中进入rip路由配置模式中使用命令redistribute igrp 101 metric 2将igrp协议重分布进rip中并设置度量值为2
进入igrp的路由配置模式使用命令redistribute rip metric 2000 将rip协议重分布进igrp中并设置度量值为2000
R1(config)#router rip
R1(config-router)#redistribute igrp 100 metric 2
R1(config)#router igrp 100
R1(config-router)#redistribute rip metric 2000
再看R2和R3的路由表
R2#sh ip route
Gateway of last resort is not set
C 192.168.4.0/24 is directly connected, Serial1/0
R 192.168.5.0/24 [120/1] via 192.168.4.1, 00:00:05, Serial1/0
R 192.168.1.0/24 [120/1] via 192.168.4.1, 00:00:05, Serial1/0
C 192.168.2.0/24 is directly connected, FastEthernet0/0
R 192.168.3.0/24 [120/2] via 192.168.4.1, 00:00:05, Serial1/0
R3#sh ip route
Gateway of last resort is not set
I 192.168.4.0/24 [100/10476] via 192.168.5.1, 00:01:04, Serial1/1
C 192.168.5.0/24 is directly connected, Serial1/1
I 192.168.1.0/24 [100/8486] via 192.168.5.1, 00:01:04, Serial1/1
I 192.168.2.0/24 [100/8576] via 192.168.5.1, 00:01:04, Serial1/1
C 192.168.3.0/24 is directly connected, FastEthernet0/0
可以看到R2和R3已经有了对方的网段的路由信息
实验测试：
R3#ping
Protocol [ip]:
Target IP address: 192.168.2.1
Source address or interface: 192.168.3.1
Sending 5, 100-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds:
Packet sent with a source address of 192.168.3.1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/24/52 ms
