华为交换机配置vlan，实现不同vlan之间互通

1. 网络拓扑图

2.开启dhcp,并创建vlan 10和vlan 20,vlan 10配置地址采取接口配置，vlan20配置地址采用全局dhcp配置。

创建vlan 10,vlan 20

[sw1]vlan batch 10 20 

配置vlan 10IP地址

[sw1]interface Vlanif 10
[sw1-Vlanif10]dis this
#
interface Vlanif10
 ip address 192.168.10.1 255.255.255.0
 dhcp select interface
 dhcp server excluded-ip-address 192.168.10.2 192.168.10.10
 dhcp server lease day 0 hour 2 minute 0
 dhcp server dns-list 114.114.114.114 8.8.8.8
 dhcp server domain-name sw1.com
#
return
[sw1-Vlanif10]

配置vlan20IP地址

[sw1]ip pool vlan20_global 
[sw1-ip-pool-vlan20_global]dis this
#
ip pool vlan20_global
 gateway-list 192.168.20.1
 network 192.168.20.0 mask 255.255.255.0
 lease day 2 hour 0 minute 0
 dns-list 223.5.5.5 223.5.5.6
#
return
[sw1-ip-pool-vlan20_global]q

3.配置GE0/0/2,GE0/0/3加入vlan 10与vlan 20

interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 10
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 20

4.配置GE0/0/1链路状态为trunk,并允许所有vlan 通过

interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094

5.结果演示，sw1交换机内的vlan 10和vlan 20之间可以互通，lsw4交换机内的vlan 10和vlan 20之间能互通，另外sw1的vlan 10与lsw4交换机的vlan 10之间也可以互通，sw1的vlan 10与lsw4交换机的vlan 20之间也可以互通

1.sw1交换机内的vlan 10和vlan 20之间可以互通

2.sw1的vlan 10与lsw4交换机的vlan 10之间也可以互通

3.sw1的vlan 10与lsw4交换机的vlan 20之间也可以互通
