         Triggered Extensions to RIP to Support Demand Circuits

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document defines a modification which can be applied to
   Bellman-Ford (distance vector) algorithm information broadcasting
   protocols - for example IP RIP, Netware RIP or Netware SAP - which
   makes it feasible to run them on connection oriented Public Data
   Networks.

   This proposal has a number of efficiency advantages over the Demand
   RIP proposal (RFC 1582).

Acknowledgements

   The authors wish to thank Richard Edmonstone of Shiva, Joahanna
   Kruger of Xyplex, Steve Waters of DEC and Guenter Roeck of Conware
   for many comments and suggestions which improved this effort.
