To use RARP services, you must set up a MAC address-to-IP address mapping
table. This table lists the MAC addresses of clients and the corresponding IP
addresses that the RARP server assigns to those clients. When a client needs to
acquire an IP address, the following interchange takes place:
1. The client broadcasts a RARP request specifying its MAC address.
2. Upon receiving a RARP request, the router refers to its MAC address-to-IP
address mapping table, then sends the client a response packet containing the
corresponding IP address.
3. The client examines the response packet to learn its IP address.
You can configure RARP support on Ethernet and token ring interfaces, and on
the Fiber Distributed Data Interface (FDDI).
