Abstract: In one embodiment, a system includes a first network, a second network, and a core network connecting the first network to the second network. The first network includes a first set of two or more network devices, wherein the first network has a first spanning tree associated therewith. Similarly, the second network includes a second set of two or more network devices, wherein the second network has a second spanning tree associated therewith, wherein the second spanning tree is separate from the first spanning tree.
