How do Mobility Groups work with internal DHCP scopes on a WLC 5508?
We have a WLC 5508 with two internal DHCP scopes which redirect to captive portals for authentication. I am looking at putting in a second WLC in a mobility group setup to provide some WLC redundancy. The LWAPs will be setup so that every second AP is on the has the second WLC as its primary controller. If the primary WLC fails we want the secondary to be able to take over and issue IP's from the internal scope. How do you set this up with a Mobility group so the second WLC does not act as a rouge DHCP server while the primary WLC is still active?
