We are using several different sizes on our Cisco 8510 controllers equally divided between our three MPLS areas, as follows:
9 - /16 9 - /19 6 - /22 6 - /23 3 - /24 - a small subnet for AppleTV devices that is going away within a month Since we use the 10. address space for wireless, and since it is a pain to change sizes in mid-stream, we set them very big and are not having any problems.

We are in the process of moving from a controllerless vendor to Aruba. Our current design is very segmented, to keep wireless device broadcasts from overwhelming the network and AP's (we had this problem back in 11g days). Presently, we've limited segments to /23's (give or take). In your controller-based environments, how large have you let these segments go? Is a /21, /20 ... viable? -Brian ____________________________________ Brian Helman, M.Ed | Director, ITS/Networking Services | *: 978.542.7272 Salem State University, 352 Lafayette St., Salem Massachusetts 01970 GPS: 42.502129, -70.894779 ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
