backbone
A group of interconnected core nodes that normally tandem traffic. A backbone node exchanges full topology information with all nodes in the same topology region that are not cluster nodes. The backbone exchanges limited routing and no topology information with clusters. The backbone does not exchange any information with nodes in other topology regions.
