Logical-Interface Support for IP Hosts with Multi-Access Support
Abstract
A logical interface is a software semantic internal to the host
operating system. This semantic is available in all popular
operating systems and is used in various protocol implementations.
Logical-interface support is required on the mobile node attached to
a Proxy Mobile IPv6 domain for leveraging various network-based
mobility management features such as inter-technology handoffs,
multihoming, and flow mobility support. This document explains the
operational details of the logical-interface construct and the
specifics on how link-layer implementations hide the physical
interfaces from the IP stack and from the network nodes on the
attached access networks. Furthermore, this document identifies the
applicability of this approach to various link-layer technologies and
analyzes the issues around it when used in conjunction with various
mobility management features.

RFC 7847 Logical-Interface Support May 2016
1. Introduction
Proxy Mobile IPv6 (PMIPv6) [RFC5213] is a network-based mobility
management protocol standardized by IETF. One of the key goals of
the PMIPv6 protocol is to enable a mobile node to perform handovers
across access networks based on different access technologies. The
protocol was also designed with the goal to allow a mobile node to
