Abstract: Techniques are disclosed for overlaying logical switch fabrics upon a physical switch fabric comprising multiple physical switch devices. In one example, a network device determines an overlay network associated with a received packet. The network device determines a logical identifier that is associated with the overlay network. In some examples, the logical identifier corresponds to a color. The network device selects a logical switch fabric that is associated with the logical identifier from a plurality of other logical switch fabrics that are overlaid upon a physical switch fabric comprising a plurality of network switch devices. The network device forwards the received packet to the selected logical switch fabric for transport across the physical switch fabric.
