Currently all devices in our remote sites are setup on 1 VLAN. We have 400 remote sites.
A project wants to split our sites into multiple VLAN's which on the whole seems like a good idea because they will be able to prevent PC's from talking to POS devices and so on.
In the current proposal, they have 5 VLAN's per site that will require DHCP.
We have 2 centralized DHCP servers for the entire environment which means I will go from having 400 scopes to 2000 scopes. Each scope is part of a Windows Server 2012 R2 DHCP Failover cluster so the numbers actually double in each case.
My questions are:
- Is there a limit to the number of DHCP Scopes I can deploy to a Windows Server 2012 R2 server? If there is, I'll need to consider adding more DHCP servers now.
- Is there another way to do my DHCP config so I can cut down on the number of scopes?
- Am I over thinking this considering we can now manage DHCP via PowerShell? We use PowerShell to manage the scopes already so we do have a level of automation we can apply.
Any advice or guidance will be appreciated. Please let me know if I need to clarify anything.
