This document describes a new approach to handling user mobility at the network layer in the context of Multi-Protocol Label Switched Networks (MPLS). This approach does not rely on the existing IP mobility management protocols such as Mobile IP, and is instead based on the combination of Multi-Protocol BGP (MP-BGP) and MPLS. This document proposes to introduce new protocol elements to MP-BGP to achieve Mobility Label distribution at the network control plane and the optimal packet delivery to the mobile node by the network forwarding plane using MPLS.
