Distributed Tunneling Configuration

The Distributed Tunneling mode, also known as AP-AP tunneling mode, is used to support L3 roaming for
wireless clients without forwarding any data traffic to the wireless switch.
In the AP-AP tunneling mode, when a client first associates with an AP in the wireless system the AP forwards
its data using the VLAN forwarding mode. The AP to which the client initially associates is the Home AP. The
AP to which the client roams is the Association AP.
When a client roams to another AP in a different subnet the Association AP tunnels all traffic from the client
to the Home AP using a CAPWAP L2 tunnel. The Home AP injects the traffic received over the tunnel into the
wired network. If a client roams to another AP in the same subnet then the tunnel is not created, and the new
AP becomes the Home AP for the client.
