华为防火墙USG基本配置

拓扑图：

交换机配置（LAV1）：

vlan batch 10 20 100  //建立VLAN
interface GigabitEthernet0/0/1 //配置端口为ACCESS与所属VLAN
 port link-type access
 port default vlan 10

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

interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 100

interface GigabitEthernet0/0/23 //配置trunk与允许VLAN,华为默认trunk不允许任何VLAN通过。
 port link-type trunk
 port trunk allow-pass vlan 10 20

interface GigabitEthernet0/0/24
 port link-type access
 port default vlan 100

AR1配置：

interface GigabitEthernet0/0/0
 ip address 202.1.1.1 255.255.255.0

ip route-static 0.0.0.0 0.0.0.0 202.1.1.254
AR2配置：

interface GigabitEthernet0/0/0
 ip address 192.168.1.1 255.255.255.0
