单臂路由实验

此实验是一个简单的单臂路由实验，实验中用到了一个cisco路由器和一个cisco交换机；交换机上配置了两个vlan，即vlan2 和vlan3，f0/24配置成trunk；路由器的f0/0连接到交换机的trunk。

路由器的配置好下：

Router#show running-config
Building configuration...

Current configuration : 475 bytes
!
version 12.2
no service password-encryption
!
hostname Router
!
!
!
!
!
ip ssh version 1
!
!
interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
!
interface FastEthernet0/0.2     定义子接口，子接口名称和此接口所属VLAN相同
 encapsulation dot1Q 2           封装协议
 ip address 1.1.1.1 255.0.0.0     配置IP地址
!
interface FastEthernet0/0.3
 encapsulation dot1Q 3
 ip address 172.16.0.1 255.255.0.0
!
interface FastEthernet0/1
 no ip address
 duplex auto
 speed auto
 shutdown
!
ip classless
!
!
!
!
!
line con 0
line vty 0 4
 login
!
!
end

在路由器中的配置中，个人觉得应注意一点，就是cisco设备在默认时每个接口都是down的，所以在进行子接口的配置时先要对物理接口进行no shutdown，而在华为设备中则不需要，因为在华为设备中默认时接口都是活动的。

交换机中的配置好下：

Switch#show running-config

end

最后进行测试：

PC>ping 172.16.0.2

Pinging 172.16.0.2 with 32 bytes of data:
