单臂路由

单臂路由原理：

路由器重新封装MAC 转换VLAN 标签

• 路由器的物理接口可以被划分成多个逻辑接口
• 每个子接口对应一个VLAN网段的网段
  单臂路由基本配置：
  交换机配置：

 <Huawei>system-view 
 [Huawei]vlan batch 10 20
 [Huawei]int Ethernet0/0/1
 [Huawei-Ethernet0/0/1]port link-type access 
 [Huawei-Ethernet0/0/1]port default  vlan 10
  [Huawei]int Ethernet0/0/2
 [Huawei-Ethernet0/0/1]port link-type access 
 [Huawei-Ethernet0/0/1]port default  vlan 20
 [Huawei]int g0/0/1
 [Huawei-GigabitEthernet0/0/1]port link-type trunk
 [Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20

路由器配置 ：

<Huawei>system-view 
[Huawei]int GigabitEthernet 0/0/0.1
[Huawei-GigabitEthernet0/0/0.1]dot1q termination vid 10
[Huawei-GigabitEthernet0/0/0.1]ip address 10.10.0.1 24
[Huawei-GigabitEthernet0/0/0.1]arp broadcast enable 

[Huawei]int GigabitEthernet 0/0/0.2
[Huawei-GigabitEthernet0/0/0.2]dot1q termination  vid  20
[Huawei-GigabitEthernet0/0/0.2]ip address 10.20.0.1 24
[Huawei-GigabitEthernet0/0/0.2]arp broadcast enable
