Technical Summary Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol that enables IP mobility for a host without requiring its participation in any mobility-related signaling. PMIPv6 requires all communications to go through the local mobility anchor. As this can be suboptimal, localized routing (LR) allows mobile nodes attached to the same or different mobile access gateways to route traffic by using localized forwarding or a direct tunnel between the gateways. This document proposes initiation, utilization and termination mechanisms for localized routing between mobile access gateways within a proxy mobile IPv6 domain. It defines two new signaling messages, Localized Routing Initiation (LRI) and Local Routing Acknowledgment (LRA), that are used to realize this mechanism. Working Group Summary This document has been presented and discussed at length in the working group. It includes multiple contributors who are listed in the Authors section. There is sufficient consensus behind the document. The authors could not agree on the tunnelling mechanism to be used between the MAGs. This has however been resolved based on the solution that is presented in RFC5949 (Fast Handovers for Proxy Mobile IPv6). Document Quality There are no known implementation of the protocol at the present time. However there is strong interest in utilizing the optimization feature in the context of network based mobility solutions. The document quality is good and provides reasonable clarity for an implementer who understands PMIP6 (RFC5213). Personnel The Document Shepherd is Basavaraj Patil, and the responsible Area Director is Brian Haberman. RFC Editor Note - Section 5.1 OLD: When the LMA receives the PBU from nMAG for MN1, it will see that localized routing is active for MN1. It MUST hence initiate LR at nMAG and update the LR state of MAG. NEW: When the LMA receives the PBU from nMAG for MN1, it will see that localized routing is active for MN1. The LMA MUST hence initiate LR at nMAG and update the LR state of pMAG. - Section 11.1 OLD: Reserved (R) This 8-bit field is unused for now. NEW: Reserved (R) This 8-bit field is unused.
