Abstract
Techniques and technologies are provided for relaying control messages between wireless switches in different mobility areas of a mobility domain. For example, the mobility domain can be divided into a first mobility area having a first designated wireless switch and a second mobility area having a second designated wireless switch. When the first designated wireless switch receives a control message from a first client wireless switch associated with the first designated wireless switch, and the first designated wireless switch can relay the control message from the first designated wireless switch to a second client wireless switch, associated with the first designated wireless switch, with which the first designated wireless switch has an internal peering session in the first mobility area.
