A software-defined network overlay capability is configured to control one or more overlay networks using software-defined networking (SDN) in which control functions and forwarding functions are separated. The software-defined network overlay capability may be configured to vertically move packets across network layers, e.g., into an overlay network (e.g., into a tunnel via encapsulation), out of an overlay network (e.g., out of a tunnel via decapsulation), or the like. The software-defined network overlay capability may be configured to move packets from native forwarding infrastructure into an overlay network, between overlay networks (e.g., into a first overlay network from a second overlay network without leaving the second overlay network, out of a first overlay network and into a second overlay network, out of a first overlay network while remaining within a second overlay network, or the like), from an overlay network onto native forwarding infrastructure, or the like.
