Techniques are provided to enable a support for guest access of devices in a network. At a controller apparatus in a first mobility sub-domain of a network comprising a plurality of mobility sub-domains, a request message containing a request for guest network access for a device is received from a first access switch in the first mobility sub-domain. The controller apparatus forwards the request message to a guest controller. At a tunneling endpoint apparatus in the first mobility sub-domain, a tunnel is established to the guest controller to carry traffic between the device and the guest controller. Traffic for the device passes in a tunnel between the first access switch and the tunneling endpoint apparatus in the first mobility sub-domain, through the tunneling endpoint apparatus in the first mobility sub-domain and in the tunnel between the routing apparatus in the first mobility sub-domain and the guest controller.
