Is it possible to have 2800 router GigE interface subnet and Integrated-Service-Engine/wlan-controller interface in same subnet by using ip unnumbered command? I'm trying not to create a new subnet for ISE, mgmt IP, and AP mgr IP. I added them along with router static routes and NM config interface commands, but I still can't browse web admin.
can you provide the "show tech-support" from the router and "show run-config" (not "show running-config") from the WLC CLI. The ISM interface needs to be on a different subnet than the mgmt and AP-manager interfaces. If the router gigE needs to be on the same subnet as the WLC management interfaces, a BVI will be needed to bridge the router and WLC interfaces together on the same subnet.
