Configuring the DHCP relay agent
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.
An MCE device serving as the DHCP relay agent can forward DHCP packets not only between a DHCP
server and clients on a public network, but also between a DHCP server and clients on a private network.
The IP address ranges of the public and private networks or those of private networks cannot overlap
each other. For more information about MCE, see MPLS Configuration Guide.
NOTE:
The DHCP relay agent configuration is supported only on Layer 3 Ethernet interfaces (or subinterfaces),
VLAN interfaces, and Layer 3 aggregate interfaces.

The DHCP server and client interact with each other in the same way regardless of whether the relay
agent exists (see
"DHCP
overview").
