I have to research the possibility of having 2 DHCP servers on the same network (e.g. the network of our university), each sending their messages to their own nodes without interference of the other one. I'm not talking about 2 DHCP servers where one is a back-up for the other one; just two servers, who have their own set of nodes to which they have to send their messages to. We have relatively little knowledge of this matter and we were told this is not easily done.
Does someone know how this could be made possible of can someone guide us to the right direction to look for?
EDIT (the collegue):
What we try to achieve is the following: We want to use OMF (http://omf.mytestbed.net/) to test some nodes in a netwerk. OMF setups the nodes (clients) via DHCP and PXE. The normal network layout for OMF is to have a separate testbed net that are attached to one router that serves as DHCP server.
We are interested in deploying some testbed nodes within the normal network topology. So say that now 15 computers in a row are attached to one router and get an address in the X.Y.Z.1-X.Y.Z-200 range. What we want to do is add 5 computers on the same router that get their address (and PXE information) from another DHCP server.
Hardcoding the MAC addresses from the large (existing) network is not a solution, it is not feasible in our case.
