配置静态路由

1.配置pc（ip 网关）

192.168.1.1 192.168.1.254

192.168.3.1 192.168.3.254

2.配置路由器

（1）设置端口ip

Router(config-if)#inter f 0/0
Router(config-if)#ip add 192.168.1.254 255.255.255.0
Router(config-if)#inter f 1/0
Router(config-if)#ip add 192.168.2.1 255.255.255.0

Router(config-if)#inter f 0/0
Router(config-if)#ip add 192.168.2.2 255.255.255.0
Router(config-if)#inter f 1/0
Router(config-if)#ip add 192.168.3.254 255.255.255.0

（2）设置路由表

ip route 192.168.3.0 255.255.255.0 192.168.2.2 

ip route 192.168.1.0 255.255.255.0 192.168.2.1

（3）查看路由表

Router#sh ip route
C    192.168.1.0/24 is directly connected, FastEthernet0/0
C    192.168.2.0/24 is directly connected, FastEthernet1/0
S    192.168.3.0/24 [1/0] via 192.168.2.2

Router#sh ip route
S    192.168.1.0/24 [1/0] via 192.168.2.1
C    192.168.2.0/24 is directly connected, FastEthernet0/0
C    192.168.3.0/24 is directly connected, FastEthernet1/0
