Internet Engineering Task Force (IETF) T. Melia, Ed. Request for Comments: 7847 Kudelski Security Category: Informational S. Gundavelli, Ed. ISSN: 2070-1721 Cisco May 2016 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.

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 toShow full document text
