Abstract
A system establishes a communication path between a mobile node and a first label edge router, registers the mobile node at the first label edge router, and creates a mobility binding at the first label edge router. The system also establishes a label switched path between the first label edge router and a second label edge router by propagating the mobility binding in the system, and establishes communication between the mobile node and a corresponding node over the label switched path. The system further maintains the communication between the mobile node and the corresponding node over the system when the mobile node moves from one physical location to another physical location and causes a handoff of the mobile node between two layer 2 grooming networks.
