Appletalk Update-Based Routing Protocol: Enhanced Appletalk Routing

Status of This Memo

This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited.

Introduction

This memo is being distributed to members of the Internet community to fully document an Apple protocol that may be running over the Internet. While the issues discussed may not be directly relevant to the research problems of the Internet, they may be interesting to a number of researchers and implementers.

About This Document

This document provides detailed information about the AppleTalk Update-based Routing Protocol (AURP) and wide area routing. AURP provides wide area routing enhancements to the AppleTalk routing protocols and is fully compatible with AppleTalk Phase 2. The organization of this document has as its basis the three major components of AURP:

AppleTalk tunneling, which allows AppleTalk data to pass through foreign networks and over point-to-point links

the propagation of AppleTalk routing information between internet routers connected through foreign networks or over point-to-point links

the presentation of AppleTalk network information by an internet router to nodes and other Phase 2-compatible routers on its local internet

What This Document Contains

The chapters of this document contain the following information:

Chapter 1, "Introduction to the AppleTalk Update-Based Routing Protocol," introduces the three major components of AURP and the

key wide area routing enhancements that AURP provides to the AppleTalk routing protocols.

Chapter 2, "Wide Area AppleTalk Connectivity," provides information about AppleTalk tunneling through IP internets and over point-to-point links.

Chapter 3, "Propagating Routing Information With the AppleTalk Update-Based Routing Protocol," describes the essential elements of AURP, including the architectural model for update-based routing. This chapter provides detailed information about the methods that AURP uses to propagate routing information between internet routers connected through tunnels.

Chapter 4, "Representing Wide Area Network Information," describes optional features of AURP-some of which can also be implemented on routers that use RTMP rather than AURP for routing-information propagation. It gives detailed information about how an exterior router represents imported network information to its local internet and to other exterior routers. It describes network hiding, device hiding, network-number remapping, clustering, loop detection, hop-count reduction, hop-count weighting, and backup paths.

The Appendix, "Implementation Details," provides information about implementing AURP.
