VLAN单臂路由

　　PC1划分至10.0.5.0网段，VLAN5；PC2划分至10.0.10.0网段，VLAN10；通过设置单臂路由，使VLAN间互通，PC1能PING同PC2；

SW1:

[SW1]vlan batch 5 10
[SW1]int GigabitEthernet 0/0/5
[SW1-GigabitEthernet0/0/5]port link-type access
[SW1-GigabitEthernet0/0/5]port default vlan 5
[SW1]int GigabitEthernet 0/0/10
[SW1-GigabitEthernet0/0/10]port link-type access
[SW1-GigabitEthernet0/0/10]port default vlan 10
[SW1]int GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type trunk
[SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 5 10
[SW1-GigabitEthernet0/0/1]undo port trunk allow-pass vlan 1

R1:

[R1]int g0/0/0.5 　　//进入子接口

[R1-GigabitEthernet0/0/0.5]dot1q termination vid 5 　　//终结指定VLAN
[R1-GigabitEthernet0/0/0.5]arp broadcast enable 　　 //开启ARP广播功能
