Abstract

In one aspect a system and method for providing communication between Ethernet and frame relay routers includes generating a unique media access control (MAC) address for a frame relay router in communication with an Ethernet router, associating the MAC address with the frame relay router, and storing the MAC address in an interworking function device (IWF). The method also includes receiving at the IWF device an address resolution protocol (ARP) request from the Ethernet router and sending from the IWF device to the Ethernet router a response to the ARP request based on the stored MAC addresses.
