1. A method, comprising:
broadcasting, from a gateway access point (GAP), a hierarchical beacon identifying the GAP as a root access point (AP) of a micro branch deployment network;
receiving, at the GAP, hierarchical beacon acknowledgements from one or more downlink APs indicating existence of the one or more downlink APs in the micro branch deployment network, wherein the hierarchical acknowledgements are responsive to iteratively modified versions of the hierarchical beacon relayed through each of the one or more downlink APs; and
discovering a topology of the micro branch deployment network based on the received hierarchical beacon acknowledgements.
