I just thought about this topic which we had brainstormed some time back, say a network is running on DHCP which serves ip address 10.205.205.0/24, now how do I introduce fail over into the system ?

Put in 2 DHCP servers with the same range ? Well, that would be nice, since there are chances of duplication of addresses. Say DHCP Srv1 gives out address 10.205.205.x and the next time, DHCP Srv2 gives out the same ip, you have fun then

So the best way to come around would be to;

1. Put 2 DHCP Servers in the network.

2. DHCP Srv1 – Make the scope from 10.205.205.1-10.205.205.100

3. DHCP Srv2 – Make the scope from 10.205.205.101-10.205.205.254

That would solve the problem, isn’t it ?
