I understand that I need to have a subnet designation where each dhcp server is to listen on. Here is my scenariissue:

I have 4 dhcp servers
Location A - serving many subnets
a2- - to be setup as failover peer for b1
Location B - serving many subnets
b2- - to be setup as failover peer for a1

How to I setup a blank subnet as a designation when I have two servers with an IP on the same subnet. In netware this wasn't an issue, I could just set a server to handle a particular subnet.

Any thoughts on how I should be getting this setup?
