两个三层交换实现不同vlan不同网段之间的通信

实验拓扑

 

实验思路：sw1 创建4个vlan  10 20 30 40  把10 20 配置0/0/1 0/0/2 PC机 
       配置trunk链路
      sw2 创建2个vlan  30 40  把30 40 配置0/0/1 0/0/2 PC机 
       配置trunk链路

 

实验步骤：
[SW1]vlan batch 10 20 30 40
[SW1]interface Vlanif 10
[SW1-Vlanif10]ip address 192.168.10.254 24
[SW1-Vlanif10]undo shutdown

 

[SW1]interface Vlanif 20
[SW1-Vlanif20]ip address 192.168.10.254 24
[SW1-Vlanif20]undo shutdown

 

[SW1]interface Vlanif 30
[SW1-Vlanif30]ip address 192.168.10.254 24
[SW1-Vlanif30]undo shutdown

 

[SW1]interface Vlanif 40
[SW1-Vlanif40]ip address 192.168.10.254 24
[SW1-Vlanif40]undo shutdown

 

[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access
[SW1-GigabitEthernet0/0/1]port default vlan 10

 

[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 20

 

[SW1]interface GigabitEthernet 0/0/5
[SW1-GigabitEthernet0/0/5]port link-type trunk
[SW1-GigabitEthernet0/0/5]port trunk allow-pass vlan 10 20 30 40

 

[SW2]vlan batch 30 40
[SW2]interface GigabitEthernet 0/0/1
[SW2-GigabitEthernet0/0/1]port link-type access
[SW2-GigabitEthernet0/0/1]port default vlan 30

 

[SW2]interface GigabitEthernet 0/0/2
[SW2-GigabitEthernet0/0/2]port link-type access
[SW2-GigabitEthernet0/0/2]port default vlan 40

 

[SW2]interface GigabitEthernet 0/0/5
[SW2-GigabitEthernet0/0/5]port link-type trunk
[SW2-GigabitEthernet0/0/5]port trunk allow-pass vlan 10 20 30 40

实验结果：
       
两个三层交换通过trunk链路 实现不同vlan不同网段之间的通信
