Abstract
A method for implementing Identity and Locator Split is provided. The method is applied in a MPLS network. ITR and ETR are also LERs in the MPLS network. The method includes: establishing a point to point LSP tunnel between ITR and ETR by running a MPLS signaling protocol; the ITR storing an EID of endpoint and RLOC mapping as well as a RLOC and outer MPLS label mapping, and forwarding the endpoint's data packets in the MPLS network based on the outer MPLS label corresponding to the RLOC. A data encapsulation method for Identity and Locator Split and a LER device in the Identity and Locator Split network are also provided in the present invention. The present invention greatly improves the encapsulation and transmission efficiency of LISP data packets in the MPLS network.
