Usage Guide
Proxy ARP helps hosts without routing information to obtain MAC addresses of other networks or
subnet IP addresses. For example, a device receives an ARP request. The IP addresses of the
request sender and receiver are in different networks. However, the device knows a route to the IP
address of the request receiver and sends an ARP response, in which the MAC address is the
Ethernet MAC address of the device itself. This process is known as proxy ARP.
Configuration
