I have three scopes setup in DHCP. Subnets 0, 1, and 2; setup with the preference of 1, 2, and 3 respectively.

Yet when I tell a client to renew its address it gets an address from subnet 1.

What is the preference for if it does not affect which scope the client gets put in?

The DHCP server is setup on all three subnets, and the router is sending advertisements on all three subnets. We are using stateful addressing.

  • What do you mean by subnets?

  • Ok. What is your expected behaviour?

  • Clients get their number from subnet 0 (or first preference), then if for some reason that subnet runs out of numbers dhcp assigns out of subnet 1, etc. Is this not the way that the preference assignment is to be used?

  • Renew it a few more times, and see what exactly happens, and post it.
