Proxy Mobile IPv6 is a network-based mobility management protocol standardized
recently in IETF. This protocol is being referenced in various system architectures
such as a protocol for building a common and access independent mobile core. Currently, there are number of extensions that are being specified for extending this protocol to support various mobility features. This document provides a brief overview of the protocol features and the deployment scenarios behind these features. Additionally, this document also identifies the developmental efforts within Cisco for building the interfaces based on Proxy Mobile IPv6 on Cisco’s mobile gateway products.
