说明：
1、用小凡搭建实验环境。
2、使用4台3640模拟路由器，1台3640模拟交换机。
3、交换机的fa0/14端口桥接真机vmnet1网卡。
IP地址的划分如下：
R1
F0/0:172.16.3.1/24
Ser1/2:192.168.4.1/24
R2
F0/0:192.168.5.2/24
Ser1/2:192.168.4.2/24
R3
F0/0:192.168.5.3/24
Ser1/1:192.168.6.3/24
R4
F0/0:172.16.7.4/24
Ser1/1:192.168.6.4/24
真机：172.16.3.2/24，网关：172.16.3.1
实验目的：
1、各路由器能学习3条route路由。
2、从真机与R4能互相ping通。
网络拓朴如下图：
实验步骤：
1、按照上图用小凡模拟接好实验环境，SW1的fa0/8与真的vmnet1网卡桥接。
2、使用SecureCRT 5.1控制台开启R1、R2、R3、R4、SW1。
3、配置各设备如下：

4、在路由器R1上做rip路由协议，并且为版式本1，如下设置：
R1(config)#router rip
R1(config-router)#network 172.16.0.0
R1(config-router)#network 192.168.4.0
R1(config-router)#exit
R1(config)#exit
R1#
*Mar 1 00:19:08.063: %SYS-5-CONFIG_I: Configured from console by console
R1#
5、在路由器R2、R3、R4上配置rip协议，并且运行版本2，如下设置：
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 192.168.4.0
R2(config-router)#network 192.168.5.0

6、使用show ip route命令查看各路由器信息：
R1#show ip route

R4#
7、在R1上的路由信息中，R1路由器已经学习到其它路由的信息，因为R1是设置版本1的rip路由协议，是可以学习到版本2的路由信息，而版本2只能学习到版本2的路由信息，所以路由器R2、R3、R4没有学习到R1的路由信息，可以使用show ip protocols查看，如所示：
R1#show ip protocols
Routing Protocol is "rip"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Sending updates every 30 seconds, next due in 17 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Redistributing: rip

R2#
8、为了让路由器R2、R3、R4也能学习到R1的路由信息，只需要在R2的ser1/2端口做如下设置就可以，因为rip路由协议是相邻路由器之间路由信息相互复制，所以只要R2路由器学习到了，其它路由器就能学习到。
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int ser1/2
R2(config-if)#ip rip re
R2(config-if)#ip rip receive v
R2(config-if)#ip rip receive version 1 2
R2(config-if)#exit
R2(config)#exit
R2#

10、再次使用show ip protocols查看：
R2#show ip protocols

Incoming update filter list for all interfaces is not set
Sending updates every 30 seconds, next due in 24 seconds
