How do i make Windows DHCP work with VLANs

[Donald Bietschek]

Hi Everybody,

I am studying for Cisco and Microsoft certifications and I am doing a practical bit in my own home network.

Here is the scoop, I have 3 Cisco rack mounted routers and 3 Cisco rack mounted switches. I also have a Windows 2012 Server running ADDS, DHCP, and DNS.

I have created 6 DHCP scopes which are as follows:

	Server Pools
ADMINISTRATION	10.227.220.1	10.227.220.100
BEDROOM	10.227.221.1	10.227.221.100
KITCHEN	10.227.222.1	10.227.222.100
BATHROOM	10.227.223.1	10.227.223.100
LIVINGROOM	10.227.224.1	10.227.224.100
WIRELESS	10.227.225.1	10.227.225.100

Basically what I want to happen is all of the switches, routers, and servers to get an address from the ADMINISTRATIVE pool. And for example if I plug a computer into the living room I want it to get an IP Address between 10.227.224.1 - 100 and the bedroom devices to get an address from the bedroom pool etc etc.

One of my admin friends told me to give VLANs a try. Is my buddy correct? Would VLANs be the best way to accomplish this, if so when I activate the scopes on the Windows server how do I get the VLANs to pass out addresses from the Windows DHCP server, I am having trouble understanding how the DHCP server and the VLANs are supposed to talk to each other and how to set that up. And last, how would i wire this physically, where would i plug in the DHCP server etc etc.

Any help would be appreciated, even a point in the right direction.

Thanks,

Donnie

Since you have the DHCP up and running and handing out IP's on one vlan my suspicion is you need to complete some vlan configuration.

The DHCP server is most likely handing out IP's only for the VLAN its switch port is assigned to.

Look at the other VLANS and see if they are setup on the switch and if they have helper addresses pointin to the DHCP servers static IP address.

On the DHCP server you must setup scopes that coincide with your VLAN's IP structure.

Once these items are complete your DHCP should be issuing IP's to the correct networks.

Where you able to solve this? My dhcp server only leases for devices within its subnet
