Router Switch Dhcp

Hi ppl.

I need some help with my problem.

I have about 120 workstations (w2k) on my network.
I want to divide a network in 5 subnets en have a DHCP on each subnet.

I have Red Hat 8 servers and for subnetting my network I don’t want to put5-6 nic’s in my server. Insted, I want to have routers that have there own DHCP servers. This way I can have DHCP on each subnet.

Now! I know that CISCO-Routers have this funcionality. But! I work for a nonprofit educational organisation, so we have to use the cheepest solutions. Cisco is not!

My question:

Is there any other cheeper solution?

Please Let me know.

Greetings,

Admir
