A method and system for path mapping through a multilevel path is disclosed. One embodiment is a process that compares a level of a start node with a level of a destination node; in response to the level of the start node being different from the level of the destination node, selects at least one preferred transition between the level of the start node and the level of the destination node; for a first plurality of nodes and respective edges on the level of the start node, determines a first best sub-path from the start node to the transition; for a second plurality of nodes and respective edges on the level of the destination node, determines a second best sub-path from the transition to the destination node; and defines a recommended path corresponding to the first best sub-path, the transition, and the second best preferred sub-path.
