交换机接入外网配置

  组网图

3.    配置步骤

3.1路由器端配置

#创建vlan

<H3C> system-view

[H3C] interface vlan 2

#配置虚接口地址，作为PC的网关

[H3C]interface  Vlan-interface 1

[H3C-Vlan-interface1] ip address 192.168.1.1 24

[H3C-Vlan-interface1] interface Vlan-interface 2

[H3C-Vlan-interface2]ip address 192.168.2.1 24

[H3C-Vlan-interface2]quit

#将与交换机互连的接口配置成trunk口，并放通所有vlan

[H3C]interface GigabitEthernet 0/2

[H3C-GigabitEthernet0/2]port link-type trunk

[H3C-GigabitEthernet0/2]port trunk  permit vlan all

#保存配置

[H3C]save force

3.2交换机端的配置

#创建vlan

<H3C>system-view

[H3C]interface vlan 2

#将连接路由器的接口切换成trunk口，并放通所有vlan

[H3C]interface  GigabitEthernet 1/0/1

[H3C-GigabitEthernet1/0/1]port link-type trunk

[H3C-GigabitEthernet1/0/1]port trunk permit vlan all

[H3C-GigabitEthernet1/0/1]quit

#将连接PC1和PC2接口划分到相应的vlan中

[H3C]interface GigabitEthernet 1/0/2

[H3C-GigabitEthernet1/0/2] port access vlan 1

[H3C-GigabitEthernet1/0/2] interface GigabitEthernet 1/0/3

[H3C-GigabitEthernet1/0/2] port access vlan 2

#保存配置

[H3C]save force
