A wireless access network includes a first access point having a first coverage area, and a second access point having a second coverage area. A portion of the second coverage area overlaps with the first coverage area in an overlapping region. The network further includes a central controller in operable communication with the first and second access points, and a single station device located within the overlapping region. The single station device is configured to connect with the first and second access points. The central controller is configured to (i) control downlink data transmission from the first and second access points, and (ii) implement a scheduling protocol for the downlink data transmission, such that the single station device receives at least a first portion of the downlink data transmission from the first access point and a second portion of the downlink data transmission from the second access point.

This technology enables a dynamic host configuration protocol ('DHCP') Layer 2 relay in a Virtual Extensible Local Area Network ('VXLAN') overlay fabric. A host device broadcasts a configuration request, such as a DHCP discover, across an Ethernet virtual private network (&#x201c;EVPN&#x201d;) overlay fabric. The DHCP discover is intercepted by a VXLAN Tunnel End Point (&#x201c;VTEP&#x201d;) device with Layer 2 bridging functionality. The VTEP device selects a centralized gateway (&#x201c;CGW&#x201d;) device with Layer 3 relay functionality as a destination for the DHCP discover. The VTEP device encapsulates the DHCP discover with a unicast VXLAN header comprising the media access control (&#x201c;MAC&#x201d;) address of the CGW device and transmits the encapsulated DHCP discover to the CGW device, resolving the destination address associated with the broadcast. The CGW device transmits the DHCP discover to an Internet Protocol (&#x201c;IP&#x201d;) address associated with a DHCP server that is external to the EVPN overlay fabric.
