1. A method comprising:
receiving, at a first non-aggregate endpoint in a first physical proximity of a virtual overlay network, a first frame from a first host device in the first physical proximity, wherein the first frame is directed to a second host device in a second physical proximity of the virtual overlay network; replicating, at the first non-aggregate endpoint, the first frame only to other non-aggregate endpoints and a first aggregate endpoint within the first physical proximity as replicated encapsulated frames; replicating, by the first aggregate endpoint, the replicated encapsulated frame to only a second aggregate endpoint in the second physical proximity and aggregate endpoints in other physical proximities of the virtual overlay network; replicating, by the second aggregate endpoint, the replicated encapsulated frame to only non-aggregate endpoints within the second physical proximity; and upon receipt of a replicated encapsulated frame sent by the second aggregate endpoint, sending, by a second non-aggregate endpoint in the second physical proximity that is connected to the second host device, the first frame to the second host device, wherein only the first and second aggregate endpoints are enabled for remote communication over a core network interconnecting the first and second physical proximities and the non-aggregate endpoints are enabled only for local communication within a physical proximity. |
