Basically what I've done is configured all of my DHCP pools on R1, one for 192.168.1.0, 192.168.2.0 and one for 192.168.3.0. The routers are interconnected with OSPF and each of the routers FA 0/0 port has an address of 192.168.x.1. The problem that I'm running into is the fact that all of the switches are receiving and forwarding an address from the 192.168.1.0 range. I assumed that the helper-address would fix this, but either I was wrong or placed it in the wrong place, or missed a step somewhere. Can anyone help me out here or at least give me a hint/ point me in the general direction of what I'm looking for.
I have this set on three actual Cisco routers and Switches, I just made a replica of the network in PT.
