Point DHCP clients to failover servers

[Jonathan Baize]

This is going to be network infrastructure specific.  If it is your
wireless controller that routes the broadcast packets from the clients then
that is where you add the additional IP.  Both servers need to get DHCP
broadcast packets, the DHCP servers have algorithms that determine who will
respond.  On routers this is typically called DHCP helper addresses.
Contact you wireless controller vendor, or network team/vendor, support for
assistance.

Hi people, I've just implemented two ISC DHCP servers in failover
configuration.

All my current DHCP clients point to Server A (primary), and now I
have also Server B (secondary).

All my DHCP clients come from a Wireless LAN Controller that points to
Server A in order to get IP addresses.

How do I have to add Server B (failover) in the Wireless Lan
Controller ??? Do I have to define any sentence in order to tell
priorities (first check Server A, after that check Server B) ???

My question in general is about failover definition in clients.

Thanks a lot, regards!!!
