Proxy Mobile IPv6 [RFC5213] describes the protocol operations to maintain reachability and session persistence for a Mobile Node (MN) without the explicit participation from the MN in signaling operations at the Internet Protocol (IP) layer. In order to facilitate such network-based mobility, the PMIPv6 protocol defines a Mobile Access Gateway (MAG), which acts as a proxy for the Mobile IPv6 [RFC6275] signaling, and the Local Mobility Anchor (LMA), which acts similar to a Home Agent. The LMA and the MAG establish a bidirectional tunnel for forwarding all data traffic belonging to the Mobile Nodes. In the case where both endpoints are located in the same PMIPv6 domain, this can be suboptimal and result in increased delay and congestion in the network. Moreover, it increases transport costs and traffic load at the LMA.

                 Localized Routing for Proxy Mobile IPv6


   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 (MNs)    attached to the same or different Mobile Access Gateways (MAGs) 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.
