DHCP relay agent functionality in ios

Does anybody know how i have to configure a Cisco 2500 with IOS-Releas 11.2(4) to act as a dhcp relay agent to forward dhcp requests to our main dhcp-server?

Thanks,

Ben

add the following statement to the interface that will relay the DHCP request.

IP Helper-Address x.x.x.x

x.x.x.x will be the IP Address of the DHCP Server.

Do you have to enable this feature on all routers in the path to the DHCP SERVER?

No just on the interfaces that you want to be able to get to the DHCP server , nothing else needs to be configured , the router just convertts the the broadcast to a unicast to the dhcp server.
