Loss of connectivity on a mesh or virtual service (e.g., VPLS) may be
restored by "stitching" a healing path between an affected node and
another node on the mesh. Connectivity may be restored by "healing" or
constructing an alternate path or connection between the affected node
and the mesh. Unidirectional and bidirectional healing may be used to
establish an alternate path between the affected node and the mesh.
Additionally, removing pseudowire connections between the affected node
and the mesh may be performed, while establishing a spoke connection to
an advertised, available router to create a new connection or "stitch"
together existing connections.
