路由综合实验
技术原理
为了支持本设备能够运行多个路由协议进程，系统软件提供了路由信息从一个路由进程重分布到另一个路由器进程的功能。
实验步骤：
1.pc与交换机间用直线连接；pc与路由、路由与路由之间用交叉线连接。
2.再三层交换机划分2个vlan，运行ripv2协议；R2运行ospf协议
3.在路由器R1上左侧配置RIPV2路由协议；右侧配置ospf协议
4.在R1路由器进程中引入外部路由，进行路由分布
5.将pc1、pc2主机默认网关分别设置为与直接网络设备接口ip地址
6.验证pc1、pc2主机之间可以互相通信

R0(config)#router ospf 1

R1配置：
Router>en
Router#config t
Enter configuration commands, one perline. End with CNTL/Z.
Router(config)#host R1
R1(config)#int fa0/1
R1(config-if)#ip address 192.168.3.2255.255.255.0

R1(config-if)#exit
R1(config)#router ospf 1

area 0
R1(config-router)#network 192.168.4.00.0.0.255 area 0
R1(config-router)#exit
R1(config)#
测试：
ping 192.168.4.2 不通；
在交换机SW0上sh ip route只能看见两条直连路由。
在R0上配置：
R0#config t
Enter configuration commands, one perline. End with CNTL/Z.
R0(config)#router rip
R0(config-router)#redistribute ospf 1
R0(config-router)#exit
R0(config)#router ospf 1
R0(config-router)#redistribute rip subnets
R0(config-router)#exit
R0(config)#
在SW0上添加静态路由：SW0(config)#ip route 0.0.0.0 0.0.0.0 192.168.2.2
就一切ok了。
