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.
