OSPF动态路由（单臂路由）

OSPF动态路由（单臂路由）

开启端口并配置IP

• RT1

Router>en
Router#conf t
Router(config)#int g0/1
Router(config-if)#no shutdown 
Router(config-if)#ip add 192.168.10.254 255.255.255.0
Router(config-if)#ex
Router(config)#int g0/0
Router(config-if)#no shutdown 
Router(config-if)#ip add 10.10.10.1 255.255.255.0

• RT2

Router>en
Router#conf t
Router(config)#int g0/0
Router(config-if)#no shutdown 
Router(config-if)#ip add 10.10.10.2 255.255.255.0
Router(config-if)#ex
Router(config)#int g0/1
Router(config-if)#no shutdown 
Router(config-if)#ip add 20.20.20.1 255.255.255.0

• RT3

Router>en
Router#conf t
Router(config)#int g0/0
Router(config-if)#no shutdown 
Router(config-if)#ip add 20.20.20.2 255.255.255.0

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

• RT4（单臂路由）

  • 二层交换机

  Switch>en
  Switch#conf t
  Switch(config)#int f0/2
  Switch(config-if)#sw acc vlan 10
  Switch(config-if)#ex
  Switch(config)#int f0/3
  Switch(config-if)#sw acc vlan 20 //将端口添加到vlan 20
  Switch(config-if)#ex
  Switch(config)#int f0/1
  Switch(config-if)#sw mo tr //更改模式为trunk
  

  • RT4路由器

  Router>en
  Router#conf t
  Router(config)#int g0/1
  Router(config-if)#no shutdown 
  Router(config-if)#ex
  Router(config)#int g0/1.1 //进入子接口，注意看是哪个端口
  Router(config-subif)#encapsulation dot1Q 10 //dotlq协议
