                             RIPng for IPv6

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 specifies a routing protocol for an IPv6 internet.  It
   is based on protocols and algorithms currently in wide use in the
   IPv4 Internet.

   This specification represents the minimum change to the Routing
   Information Protocol (RIP), as specified in RFC 1058 [1] and RFC 1723
   [2], necessary for operation over IPv6 [3].

Acknowledgements

   This document is a modified version of RFC 1058, written by Chuck
   Hedrick [1].  The modifications reflect RIP-2 and IPv6 enhancements,
   but the original wording is his.

   We'd like to thank Dennis Ferguson and Thomas Narten for their input.
