Configuring the DHCP relay agent

The DHCP relay agent configuration is supported only on VLAN interfaces.

Overview

The DHCP relay agent enables clients to get IP addresses from a DHCP server on another subnet. This
feature avoids deploying a DHCP server for each subnet, centralizes management, and reduces
investment.

Fundamentals

Figure 23 shows a typical application of the DHCP relay agent.
Figure 23 DHCP relay agent application
The DHCP server and client interact with each other in the same way regardless of whether the relay
agent exists (see
Figure 24 DHCP relay agent work process
"DHCP address allocation").
