Claim:
A method comprising: registering a mobile node at a first label edge router by creating, at the first label edge router, a mobility binding that associates a mobility label and an area identifier (ID) that identifies a geographical area; establishing a communication path between the mobile node registered at the first label edge router and the first label edge router; establishing a first label switched path between the first label edge router and a first area label edge router associated with a first geographical area and a first area ID; establishing a second label switched path between a second label edge router and a second area label edge router; establishing a third label switched path between the first area label edge router and the second area label edge router; establishing communication between the mobile node and a corresponding node over the first label switched path, the second label switched path, and the third label switched path; and maintaining the communication between the mobile node and the corresponding node when the mobile node moves from one physical location to another physical location, wherein the first label edge router is associated with a first region, and wherein the first geographical area includes the first region.
