Abstract

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in the Internet
   community.  In particular, it describes managed objects related to
   the forwarding of Internet Protocol (IP) packets in an IP version-
   independent manner.  This document obsoletes RFC 2096.

1.  Introduction

   This document defines a portion of the Management Information Base
   (MIB) for use in managing objects related to the forwarding of
   Internet Protocol (IP) packets in an IP version-independent manner.

   It should be noted that the MIB definition described herein does not
   support multiple instances based on the same address family type.
   However, it does support an instance of the MIB per address family.

2.  Conventions Used In This Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

3.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

4.  Overview

   The MIB consists of one current table and two current global objects.

      1. The object inetCidrRouteNumber indicates the number of current
         routes.  This is primarily to avoid having to read the table in
         order to determine this number.

      2. The object inetCidrRouteDiscards counts the number of valid
         routes that were discarded from inetCidrRouteTable for any
         reason.  This object replaces the ipRoutingDiscards and
         ipv6DiscardedRoutes objects.

      3. The inetCidrRouteTable provides the ability to display IP
         version-independent multipath CIDR routes.
