Mobility Support Using MPLS and MP-BGP Signaling
This document describes a new approach to handling user mobility at the network layer in the context of Multiprotocol 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 Multiprotocol 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.
