A network may include a first set of routers at a first level of a multi-protocol label switched tunneling hierarchy and a second set of routers at a second level of the multi-protocol label switched tunneling hierarchy, the second set of routers connected to the first set of routers in a partially meshed topology. The network may also include a hierarchical segmented label switched path. The hierarchical segmented label switched path may include a forwarding adjacency label switched path including a subset of the first set of routers, and a label switched path coupled to the forwarding adjacency label switched path, the label switched path including a subset of the second set of routers. |
