RFC 1390 IP Over FDDI January 1993 Introduction The goal of this specification is to allow compatible and interoperable implementations for transmitting IP datagrams [1] and ARP requests and replies [2]. The Fiber Distributed Data Interface (FDDI) specifications define a family of standards for Local Area Networks (LANs) that provides the Physical Layer and Media Access Control Sublayer of the Data Link Layer as defined by the ISO Open System Interconnection Reference Model (ISO/OSI). Documents are in various stages of progression toward International Standardization for Media Access Control (MAC) [4], Physical Layer Protocol (PHY) [5], Physical Layer Medium Dependent (PMD) [6], and Station Management (SMT) [7]. The family of FDDI standards corresponds to the IEEE 802 MAC layer standards [8, 9, 10]. The remainder of the Data Link Service is provided by the IEEE 802.2 Logical Link Control (LLC) service [11]. The resulting stack of services appears as follows: +-------------+ | IP/ARP | +-------------+ | 802.2 LLC | +-------------+-----+ | FDDI MAC | F | +-------------+ D S | | FDDI PHY | D M | +-------------+ I T | | FDDI PMD | | +-------------+-----+ This memo describes the use of IP and ARP in this environment. At this time, it is not necessary that the use of IP and ARP be consistent between FDDI and IEEE 802 networks, but it is the intent of this memo not to preclude Data Link Layer interoperability at such time as the standards define it. It is the explicit intent of this memo to allow the interoperability of IP and ARP between stations on FDDI networks and stations on Ethernet networks via translational bridges. The FDDI standards define both single and dual MAC stations. This document describes the use of IP and ARP on single MAC stations (single-attach or dual-attach) only. Katz
