install the dhcp package.
rpm -ivh dhcp-3
edit the file /etc/sysconfig/dhcrelay
on INTERFACES specify the interface on which to listen for requests
on DHCPSERVERS specify the ip of the server to forward the requests.
start the service:
service dhcrelay start

assign points.

Please, can you explain me this agent?

It's the same agent that a Dhcp client?

Thanks in advance.

Regards!

No, it isn't.

A DHCP relay agent is a DHCP server that forward requests to another DHCP server. This is used when you have a network separated by a router, and the router does not forwards bootp traffic:

network A -----------router---------network B

If the DHCP server is in network A, and network B should get address from that server, you must configure a DHCP relay agent on a server in network B, so clients query for DHCP server, DHCP relay forwards the request to the DHCP server, and then returns the IP to the client.
