If a client’s request is invalid (for example, when the client has moved to a new

network), servers respond with a DHCPNAK packet. If a client receives only a

DHCPNAK packet, it must request a new IP address by broadcasting a

DHCPDISCOVER packet.

RARP Overview

You can use a Bay Networks router as a Reverse Address Resolution Protocol

(RARP) server that assigns IP addresses to its clients on the local area network.

When you configure a router to use RARP services, it acts as a RARP server. A

RARP server supplies clients on the same physical or logical LAN with IP

addresses (Figure 2-11)
