Appletalk Update-Based Routing Protocol: Enhanced Appletalk Routing

RFC 1504        Appletalk Update-Based Routing Protocol      August 1993


      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.

What You Need to Know

   This document is intended for developers of AppleTalk wide area
   routing products. It assumes familiarity with the AppleTalk network
   system, internet routing, and wide area networking terms and
   concepts.
