Multiple DHCP server problem [UNSOLVABLE]

[r00t440]

Hello Networking experts! On our company each department have the freedom to acquire their own internet connection. Most of the time each depart purchases a router, and they have this habit of just plugging everything to the our main network. This makes the main network to have multiple DHCP servers which "confuses" the clients, sometimes these workstations acquire the wrong IP preventing them to access the services from the main network. How do I set my network so that all workstations acquires their IP from the main DHCP server.

Thanks in advance.

You don't, unfortunately.

There have been talks on OTW of network admins almost biting people's heads off after figuring out that a router was plugged in backwards. Lot's of not fun weekends for them.

To solve your problem, assume your network has a main router, with points coming off of it. That has a DHCP server (or there's a DHCP server on that level). Routers beyond that should interface to that network through the "internet" port on the router (might be called other things). That makes the routers act as dhcp clients to the main network, and DHCP servers only to the parts of the network below them.


I'll clarify if you need me to.... just ask

Thanks guys for your inputs... Then I guess I have to isolate each department from others or strictly forbid them from plugging a router(reverse) to the main network. Maybe I should mark this as "UNSOLVABLE".
