多个路由器互通（静态路由）无单臂路由（简单版）

开启端口并配ip地址

维护1

Router>en
Router#conf t
Router(config)#int g0/0
Router(config-if)#no shutdown 
Router(config-if)#ip address 192.168.10.254 255.255.255.0

Router(config)#int g0/1
Router(config-if)#no shutdown 
Router(config-if)#ip address 30.30.30.1 255.255.255.0

维护中转（要看清哪个端口对应哪个ip地址）

Router(config-if)#ip address 20.20.20.2 255.255.255.0

Router(config-if)#no shutdown 
Router(config-if)#ip address 10.10.10.2 255.255.255.0

运用静态路由让电脑互相通讯

维护中转（需要写维护1-维护3的中转过程）
这些虽表明是哪台维护电脑的，但操作是在维护中转进行操纵（下面备注是让明白从哪里出发）
