静态路由、缺省路由的配制...

 

实验目的：三台路由连接5个网段，配置静态路由和缺省路由

拓扑图：

Router>en

Router#conf t

Router(config)#host R1

R1 (config)#int e0                                             进入e0端口

R1(config-if)#ip add 172.16.3.1 255.255.255.0                    添加e0口的IP

R1(config-if)#no shut                                          打开e0口

R1(config-if)#exit

R1(config)#int s0                                             进入s0端口

R1(config-if)#ip add 172.16.1.1  255.255.255.0                    添加s0口的IP

R1(config-if)#clock rate 56000                                  设置时钟

R1(config-if)#no shut                                          打开s0口

R1(config-if)#exit

R1(config)#ip route 0.0.0.0  0.0.0.0    172.16.1.2                 添加缺省路由

R2 (config-if)#ip add172.16.4.1  255.255.255.0                    添加e0口的IP

R2 (config-if)#no shut                                         打开e0口

R2 (config-if)#exit

R2 (config)#int s1                                             进入s1端口

R2 (config-if)#exit

R2 (config)#ip route 172.16.3.0 255.255.255.0172.16.1.1            添加静态路由

R2 (config)#ip route 172.16.5.0 255.255.255.0172.16.2.2            添加静态路由

R3 (config-if)#exit

R3 (config)#ip route 0.0.0.0  0.0.0.0  172.16.2.1                   添加缺省路由
