Does a reservation create an exclusion?

[JBruyet]

Hey all,

Does creating a "Reservation" on one DHCP server create some type of "Exclusion" on the other DHCP server in my small domain?

Here's the situation: I set static IP addresses on all servers/computers that I use for "working" in the network. That way I'll always know how to access them using my Cisco VPN from home. My assistant recently assigned a reservation to a workstation on the first DHCP server and I was wondering if my second DHCP server would try to offer it an address later on, even though it has a reservation from the first DHCP server. Just wondering...

Thanks,

Joe B

No. When the computer boots up and asks for an IP address, the reservation will take precedence.

There are no more PDC's! There are DC's with FSMO roles!

Good, that's what I was hoping for.

The reservation can be outside of the scope range, though.

58sniper,

That's good. I never thought to mention that I have my two DHCP servers offering up half of the addresses (I call it top half and bottom half).

Thanks,

There are assumptions that have to be made...the first one being that you were splitting your scope between the two servers, and second that the assigned IP would be within a proper range.

I suppose if we're going to worry that the IP is assigned properly, we should also worry that a switch may go down causing the system to get an IP from the other scope...or a meteor shower may cause a temporary rift in time at your location, or...
