Configuring DHCP Relay

Overview

The Dynamic Host Configuration Protocol (DHCP) is used for configuring

hosts with IP address and other configuration parameters without user inter-

vention. The protocol is composed of three components:

■ DHCP client

■ DHCP server

■ DHCP relay agent

The DHCP client sends broadcast request packets to the network; the DHCP

servers respond with broadcast packets that offer IP parameters, such as an

IP address for the client. After the client chooses the IP parameters, commu-

nication between the client and server is by unicast packets.

ProCurve routing switches provide the DHCP relay agent to enable commu-

nication from a DHCP server to DHCP clients on subnets other than the one

the server resides on. The DHCP relay agent transfers DHCP messages from

DHCP clients located on a subnet without a DHCP server to other subnets. It

also relays answers from DHCP servers to DHCP clients.
