Method for Mobile Node to Dynamically Acquire Location Identifier, and Lisp Network

摘要

A method for a mobile node dynamically obtaining a location identifier, and a locator/ID separation protocol (LISP) network are provided. The method is applied in the LISP network, including: when a mobile node moves to a new location, sending an address information allocation request including a first option to an address information allocation device, wherein, the first option includes attribute information of which a value represents globally routable; after receiving the address information allocation request, the address information allocation device preferentially selecting globally routable address information in locally available address information resources, and then replying with an address information allocation response carrying the selected address information to the mobile node, wherein the address information includes an address or a routing prefix.
