    PCA:172.16.0.2 255.255.0.0

    PCB:172.16.1.2 255.255.0.0

    RTA:G0/0:172.16.0.1 255.255.255.0

            G0/1:172.16.1.1 255.255.255.0

    利用ARP代理使两个子网互访；

    [RTA]interface G0/0

             ip address 172.16.0.1 24

             proxy-arp enable                         开启ARP代理功能

             interface G0/1

             proxy-arp enable

    此时RTA的ARP表上有两边PC的IP和MAC地址信息。

    [H3C]disp arp all
                    Type: S-Static    D-Dynamic    A-Authorized
    IP Address       MAC Address     VLAN ID  Interface              Aging Type
    172.16.1.2       00e0-0400-1100  N/A      Eth0/0/0               12    D
    172.16.0.2       000c-29b7-2033  N/A      Eth0/1/0               12    D

    此时PCA和PCB可以通过ARP代理广播相互访问：

    C:\Documents and Settings\xiaofei>ping 172.16.1.2
