You can have multiple anchor wlc in the DMZ. These will always have a different mobility group name than your foreign wlc's. There is no pre-empt in a multiple anchor wlc. I believe with 5.2 you can specify which anchor wlc you want traffic to go to, but then again, I don't like any of the 5.x code. With the 4.x and earlier versions of the 5.x code, the decision on where traffic will go to is calculated by the foreign wlc that has to anchor the trafic to one of the anchor wlc's in the DMZ. Local WLC uses these anchor wlc's in the order WLCs are configuredIs failover transparent to the user.... no. Since best practice is to make sure your dhcp scopes on the wlc do not overlap, users who is anchored to one that fails, will move to the other wlc. This usually will make the client renew its dhcp address.
