配置静态路由实现两个不同网络之间的全网互通
1）搭建网络拓扑
2）配置PC1的IP地址为192.168.1.1，网关为192.168.1.254
配置PC2的IP地址为192.168.2.1，网关为192.168.2.254
3）router1上配置接口IP
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.1.254 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface fastEthernet 0/1
R1(config-if)#ip address 192.168.2.1 255.255.255.0
R1(config-if)#no shutdown
4）router2上配置接口IP
R2(config)#interface fastEthernet 0/1
R2(config-if)#ip address 192.168.2.2 255.255.255.0
R2(config-if)#no shutdown
R2config-if)#exit
R2(config)#interface fastEthernet 0/0
R2(config-if)#ip address 192.168.3.254 255.255.255.0
R2(config-if)#no shutdown
5）在router1上添加静态路由并产看路由表
R1(config)#ip route 192.168.3.0 255.255.255.0 192.168.2.2
R1#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
