We have multiple sites all on different subnets, we have one central DHCP server which I want to change (so I can do maintenance).
I want to add a second DHCP server (for redundancy) but I can only broadcast one helper address from the site routers. I have read up on virtual IP's but am unsure if this is the correct way to go.
We have multiple DC's in different geographical locations
Routers are part of our MPLS so I cannot make changes (I can have the helper add changed)
All servers are in the hosted data center (VM's)
All help/advice gratefully received.
