1. An apparatus, comprising:

  • a switch fabric;

    a controller operatively coupled to the switch fabric; and

    a plurality of edge devices operatively coupled to an edge of the switch fabric such that each edge device from the plurality of edge devices is a single logical hop from the remaining edge devices from the plurality of edge devices via the switch fabric, the controller configured to emulate a virtual multi-hop network topology within the switch fabric and the plurality of edge devices,the plurality of edge devices and the switch fabric collectively define at least a portion of a switch core defining a single logical entity,the controller is configured to store a first routing information representing a single-hop topology of the plurality of edge devices, the controller is configured to store a second routing information representing the virtual multi-hop network topology,the second routing information is associated with routing data executed outside of the switch core, the first routing information is associated with routing of the data executed within the switch core.
