H3C设备之ARP代理

2023-01-31 03:01:07 设备 代理 H3C

 

 

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:
