DHCP scope for more than one controllers

Unanswered Question

I am using three wireless LAN controllers for my network. I am distributing the IP addresses to the clients by using the internal DHCP of the controllers. These controllers are in the same mobility group. Do I have to make the same DHCP scope configuration on each controller or should I make it only on one of them. By applying the same configuration and IP pool on both three controllers, will the controllers start distributing the same IP addresses and create IP reuse problem?

Thanks for the help.

Yes, you will have to create a scope on each controller.  I would suggest that you don't use the same scope on each one.  Just break the scope up between them.  For example use x.x.x.100 to x.x.x.199 on one controller, then use x.x.x.200 to x.x.x.254 on the other controller.  The DHCP servers built into the controllers are very basic.

So I will split the pool between three controllers to prevent ip-reuse.

Thanks for the reply.
