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 to centralize management and reduce investment. Figure 26 shows a typical application of the DHCP relay agent.

An MCE device acting as the DHCP relay agent can forward DHCP packets between a DHCP server and clients on either a public network or a private network. For more information about MCE, see MPLS Configuration Guide.
