通过配置trunk链路和配置网关实现全网互通

实验目的：192.168.10.X 与 192.168.20.X 进行通信

实验拓扑:

实验步骤：

[SW1]vlan batch 2 3    //创建vlan

[SW1]interface GigabitEthernet 0/0/1   //进入接口

[SW1-GigabitEthernet0/0/1]port link-type access  //改为Access链路

[SW1-GigabitEthernet0/0/1]port default vlan 2   //加入vlan 2

[SW1]interface GigabitEthernet 0/0/2

[SW1-GigabitEthernet0/0/2]port link-type access

[SW1]-GigabitEthernet0/0/2]port default vlan 3

[SW1]interface Vlanif 2   //进入vlan 2

[SW1-Vlanif2]ip address 192.168.10.254 24  //设置IP地址

[SW1-Vlanif2]undo shutdown  //开启端口

[SW1]interface Vlanif 3

[SW1-Vlanif3]ip address 192.168.20.254 24

[SW1-Vlanif3]undo shutdown

[SW1]interface GigabitEthernet 0/0/6  //进入接口

[SW1-GigabitEthernet0/0/6]port link-type trunk  //改为trunk链路

[SW1-GigabitEthernet0/0/6]port trunk allow-pass vlan 2 3  // 加入 vlan 2  3

[SW2]interface GigabitEthernet 0/0/2

[SW2-GigabitEthernet0/0/2]port link-type access

[SW2]-GigabitEthernet0/0/2]port default vlan 3

[SW2]interface GigabitEthernet 0/0/6  

[SW2-GigabitEthernet0/0/6]port link-type trunk  

[SW2-GigabitEthernet0/0/6]port trunk allow-pass vlan 2 3
