3.1 Introduction to DHCP Relay Agent

Since the packets are broadcasted in the process of obtaining IP addresses, DHCP is

only applicable to the situation that DHCP clients and DHCP servers are in the same

network segment, that is, you need to deploy at least one DHCP server for each

network segment, which is far from economical.

The DHCP relay agent is designed to address this problem. It enables DHCP clients

in a subnet to communicate with the DHCP server in another subnet so that the DHCP

clients can obtain IP addresses. In this case, the DHCP clients in multiple networks

can use the same DHCP server, which can decrease your cost and provide a

centralized administration.
