Relay agent configurations

There are several relay agent configuration options available if you plan to incorporate a relay agent into your DHCP/BOOTP-enabled network. These options include using non-Microsoft routers, Windows Server 2003 Routing and Remote Access service, and the DHCP Relay Agent component provided in Windows NT Server 4.0.

Non-Microsoft router

This example shows a non-Microsoft router configuration. The router is running a relay agent forwarding DHCP requests between Subnet A and Subnet B. Typically, the relay agent on the router must be configured with the IP address of the DHCP server.

The Routing and Remote Access service

This example shows the Windows Server 2003 Routing and Remote Access configuration. The DHCP Relay Agent in the Windows Server 2003 family must be configured with the IP address of the DHCP server in order to relay DHCP requests between Subnet A and Subnet B. For more information about setting up the DHCP Relay Agent, see Configure the DHCP Relay Agent.
