                    RIP Version 2 Protocol Analysis

Status of this Memo

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

Abstract

   As required by Routing Protocol Criteria (RFC 1264), this report
   documents the key features of the RIP-2 protocol and the current
   implementation experience.  This report is a prerequisite to
   advancing RIP-2 on the standards track.

Acknowledgements

   The RIP-2 protocol owes much to those who participated in the RIP-2
   working group.  A special thanks goes to Fred Baker, for his help on
   the MIB, and to Jeffrey Honig, for all his comments.

1.  Protocol Documents

   The RIP-2 applicability statement is defined in RFC 1722 [1].

   The RIP-2 protocol description is defined in RFC 1723 [2].  This memo
   obsoletes RFC 1388, which specifies an update to the "Routing
   Information Protocol" RFC 1058 (STD 34).

   The RIP-2 MIB description is defined in RFC 1724 [3].  This memo
   obsoletes RFC 1389.

2.  Key Features

   While RIP-2 shares the same basic algorithms as RIP-1, it supports
   several new features.  They are: external route tags, subnet masks,
   next hop addresses, and authentication.

   The significant change from RFC 1388 is the removal of the domain
   field.  There was no clear agreement as to how the field would be
   used, so it was determined to leave the field reserved for future
   expansion.
