             RIP Version 2 Protocol Applicability Statement

Status of this Memo(RFC1661に同じ)

Abstract

   As required by Routing Protocol Criteria (RFC 1264), this report
   defines the applicability of the RIP-2 protocol within the Internet.
   This report is a prerequisite to advancing RIP-2 on the standards
   track.

1.  Protocol Documents

   The RIP-2 protocol analysis is documented in RFC 1721 [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 will
   obsolete RFC 1389.

2.  Introduction

   This report describes how RIP-2 may be useful within the Internet.
   In essence, the environments in which RIP-2 is the IGP of choice is a
   superset of the environments in which RIP-1, as defined in RFC 1058
   [1], has traditionally been used.  It is important to remember that
   RIP-2 is an extension to RIP-1; RIP-2 is not a new protocol.  Thus,
   the operational aspects of distance-vector routing protocols, and
   RIP-1 in particular, within an autonomous system are well understood.

   It should be noted that RIP-2 is not intended to be a substitute for
   OSPF in large autonomous systems; the restrictions on AS diameter and
   complexity which applied to RIP-1 also apply to RIP-2.  Rather, RIP-2
   allows the smaller, simpler, distance-vector protocol to be used in
   environments which require authentication or the use of variable
   length subnet masks, but are not of a size or complexity which
   require the use of the larger, more complex, link-state protocol.

   The remainder of this report describes how each of the extensions to
   RIP-1 may be used to increase the overall usefullness of RIP-2.
