路由式 ， 路由可达，如果开启arp-proxy数据包就会送到三层去处理，子网掩码会在计算机系统中起作用，子网掩码需要仔细理解他只会限制自己的网卡的意思。


1.创建VLAN，将接口加入VLAN，并配置接口的IP地址 

# 配置Switch_1。
<HUAWEI> system-view
[HUAWEI] sysname Switch_1
[Switch_1] vlan batch 10
[Switch_1] interface gigabitethernet 0/0/1
[Switch_1-GigabitEthernet0/0/1] port link-type access
[Switch_1-GigabitEthernet0/0/1] port default vlan 10
[Switch_1-GigabitEthernet0/0/1] quit
[Switch_1] interface vlanif 10
[Switch_1-Vlanif10] ip address 172.16.1.1 24


# 配置Switch_2。
<HUAWEI> system-view
[HUAWEI] sysname Switch_2
[Switch_2] vlan batch 20
[Switch_2] interface gigabitethernet 0/0/1
[Switch_2-GigabitEthernet0/0/1] port link-type access
[Switch_2-GigabitEthernet0/0/1] port default vlan 20
[Switch_2-GigabitEthernet0/0/1] quit
[Switch_2] interface vlanif 20
[Switch_2-Vlanif20] ip address 172.16.2.1 24



2.配置路由式Proxy ARP 

# 配置Switch_1。
[Switch_1-Vlanif10] arp-proxy enable
[Switch_1-Vlanif10] quit

# 配置Switch_2。
[Switch_2-Vlanif20] arp-proxy enable
[Switch_2-Vlanif20] quit


3.验证配置结果 

# 在Switch_1上查看VLANIF10接口的ARP表项，可以看到VLANIF10接口的IP地址对应的MAC地址。
[Switch_1] display arp interface vlanif 10
