终端跨二层交换机连接三层网关设备进行通信

1、创建vlan <SWITCHA>system-view //进入系统模式

[SWITCHA]vlan batch 2 3 //批量新建vlan 2 和3

2、创建vlanif三层接口作为PC电脑的网关IP地址

[SWITCHA] interface Vlanif 2 //进入三层vlanif10接口

[SWITCHA-Vlanif2] ip address 1.1.1.1 255.255.255.0 //此IP地址为HOSTA/B对应网关地址

[SWITCHA-Vlanif2] quit //退出vlanif2接口

[SWITCHA] interface Vlanif 3

[SWITCHA-Vlanif3] ip address 2.2.2.1 255.255.255.0 //此IP地址为HOSTC/D对应网关地址

[SWITCHA-Vlanif3] quit

3、接口加入相应vlan，SwitchA-----trunk------SwitchB

[SWITCHA] interface GigabitEthernet 0/0/1

[SWITCHA-GigabitEthernet0/0/1] port link-type trunk //链路类型为trunk

[SWITCHA-GigabitEthernet0/0/1] port trunk allow-pass 2 to 3 //将接口划分到VLAN 2和vlan3中

[SWITCHA-GigabitEthernet0/0/1] quit

1、创建vlan

<SWITCHB> system-view //进入系统模式

[SWITCHB] vlan batch 2 3 //批量新建vlan 2 和3

2、接口加入相应vlan，SwitchB-----trunk------SwitchA

[SWITCHB] interface GigabitEthernet 0/0/1 [SWITCHB-GigabitEthernet0/0/1] port link-type trunk //链路类型为trunk

[SWITCHB-GigabitEthernet0/0/1] port trunk allow-pass 2 to 3 //将接口划分到VLAN 2和vlan3中

[SWITCHB-GigabitEthernet0/0/1] quit

3、接口加入相应vlan，SwitchB---access---HOST，HOSTA和HOSTB配置一样

[SWITCHB] interface Ethernet 0/0/2

[SWITCHB-Ethernet0/0/2] port link-type access //链路类型为access

[SWITCHB-Ethernet0/0/2] port default vlan 2 //将HOSTA划分到vlan2中

[SWITCHB-Ethernet0/0/2] quit

4、接口加入相应vlan，SwitchB---access---HOST，HOSTC和HOSTD配置一样，C和D配置一样

[SWITCHB] interface Ethernet 0/0/4

[SWITCHB-Ethernet0/0/4] port link-type access //链路类型为access

[SWITCHB-Ethernet0/0/4] port default vlan 3 //将HOSTC划分到vlan3中

[SWITCHB-Ethernet0/0/3] quit
