We are looking into how we can provide DHCP redundancy in particular using an automatic switching method. At the moment, we have one server acting as a DHCP server and another as a backup DHCP server, with a copy of the DHCP scope. The problem with this method is that we have to manually reconfigure the IP Helper on the switches and manually activate the backup DHCP scopes when the main DHCP server goes down but we want to automate this process.
Is there a method we can employ to do this?

split scopes is the only real way to provide dhcp redundancy.. it’s not something that lends itself
although, on your spare server – just add the correct IP to the interface when the main line goes down

If you have Server 2012 you have DHCP failover as an option (http://technet.microsoft.com/en-us/library/dn338978.aspx)
Basically multiple DHCP server get the same scope (automatically copied from one to the other) and manage issuing addresses between them
Far superior to split scopesNovember 19, 2014 at 12:40 am #359918Re: Automatic DHCP switching when active DHCP server goes down

Far superior to split scopesooh, cool, thanks !
but i’m assuming it only shares with 2k12, not with anything else ? -
