A system includes a label edge router associated with a geographical region, an area label edge router associated with an area that includes the region, and a route reflector associated with the area. The label edge router registers a first mobile node, creates a mobility binding for the first mobile node, and sends a first internal update message that includes the mobility binding. The area label edge router receives a second internal update message that carries contents of the first internal update message, updates a forwarding information base based on the second internal update message to establish a first label switched path, and sends an external update message. The route reflector receives the first internal update message, sends the second internal update message to the area label edge router, and receives the external update message from the area label edge router. |
