Currently I have 2 4400 controllers in my head office site and we want to break them up for DR purposes. I want to put one in HO and one in an office 100 km away. We have a MPLS connection in between the two offices at 40mb.
At HO I have an anchor controller providing guest internet access via DSL and 3 WLANs for internal users.
The idea in splitting these controllers up is to have all ap's in the HO area to be hosted from the HO wlc and all others in the province to be hosted from the second controller. we did not want to change the ip information or create new WLANs if possible.
What is the recommended practice for this type of scenario???
