静态路由配置路由表 路由器实现单臂路由 三层交换机实现单臂路由

配置代码
三层交换机：
注意：F0/1接口的配置是一个三层交换机实现单臂路由的模型：
1：配置二层交换机、划分vlan、设置trunk 
En
Conf t
Host s1
Vlan 2
Exit
Vlan 3
Exit
Int f0/1
Switchport access vlan 2
Int f0/2
Switchport access vlan 3
Int f0/3
Switchport mode trunk

2:三层交换机
En
Conf t
Host s3
Vlan 2
Exit
Vlan 3
Exit
Int vlan 2
Ip address 192.168.1.254 255.255.255.0     —–ip为pc的网关
Exit
Int vlan 3
Ip address 192.168.2.254 255.255.255.0     —–ip为pc的网关
Int f0/1
Switchport mode access      ——该命令是为了能设置下一条命令否则设置不成功

Switchport mode trunk
Ip routing         —–开启路由
Int f0/3
No switchport      ----三层交换机接口升为三层口
Ip address 192.168.0.254 255.255.255.0
Int f0/2   
No switchport      ----三层交换机接口升为三层口
Ip address 192.168.5.1 255.255.255.252
Ip route 192.168.3.0 255.255.255.0 192.168.5.2     ---设置静态路由
Ip route 192.168.4.0 255.255.255.0 192.168.5.2

路由器r1：
注意：F0/0接口是路由器实现单臂路由的模型，划分子接口：
1：配置二层交换机、划分vlan、设置trunk
