网络技术-利用静态路由实现网络互通-3（1）

已补

1，利用静态路由实现网络互通（两个公司互相通信）

完整图：

2，配置路由器

2.1，此时可以看到电脑和路由器之间是红色的，即不可通信，解决：

Router(config)#interface fa0/0
Router(config-if)#no shutdown 
Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

2.2，此时ping本机IP即可正常通信

2.3，分别启用两台路由器的serial 0/0/0接口

Router(config)#interface serial 0/0/0 
Router(config-if)#no shutdown 
Router(config-if)#
%LINK-5-CHANGED: Interface Serial0/0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0/0, changed state to up

2.4，设置路由器的网关

路由器0

Router(config)#interface fa 0/0
Router(config-if)#ip address 192.168.1.1 255.255.255.0 # 设置此IP地址为本网段的网关

路由器1

Router(config)#interface fa0/0
Router(config-if)#ip address 10.1.1.1 255.255.255.0

此时，PC电脑即可与路由器通信

2.5，配置路由表（路由表是表达到达目的地的下一跳地址）

路线0：

Router(config)#ip route 10.1.1.0 255.255.255.0 2.2.2.2

路线1：

Router(config)#ip route 192.168.1.0 255.255.255.0 2.2.2.3

此时，即可相互通信：
