Abstract

Techniques are provided for configuring wireless switches within a mobility domain. In one implementation, a first designated wireless switch and a first client wireless switch are configured as part of a first mobility area of the mobility domain. An internal peering session is established between the first client wireless switch and the first designated wireless switch in the first mobility area. A second designated wireless switch is configured as part of a second mobility area of the mobility domain, and an external peering session is established between the first designated wireless switch in the first mobility area and the second designated wireless switch in the second mobility area. Other techniques are provided for relaying control messages between wireless switches in different mobility areas of a mobility domain. Techniques are also provided for resolving conflicts among wireless switches associated with a wireless client device regarding a layer 3 (L3) mobility state of the wireless client device at the wireless switches.
