                Definitions of Managed Objects for BGP-4

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 memo 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 used for managing the
   Border Gateway Protocol Version 4 or lower.

   The origin of this memo is from RFC 1269 "Definitions of Managed
   Objects for the Border Gateway Protocol (Version 3)", which was
   updated to support BGP-4 in RFC 1657.  This memo fixes errors
   introduced when the MIB module was converted to use the SMIv2
   language.  This memo also updates references to the current SNMP
   framework documents.

   This memo is intended to document deployed implementations of this
   MIB module in a historical context, to provide clarifications of some
   items, and to note errors where the MIB module fails to fully
   represent the BGP protocol.  Work is currently in progress to replace
   this MIB module with a new one representing the current state of the
   BGP protocol and its extensions.

   This document obsoletes RFC 1269 and RFC 1657.

1.  Introduction

   This memo 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 used for managing the
   Border Gateway Protocol Version 4 or lower [BGP4, BGP4APP].

   This memo obsoletes RFC 1657 and RFC 1269.

2.  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].

3.  Overview

   These objects are used to control and manage a BGP-4 implementation.

   Apart from a few system-wide scalar objects, this MIB is broken into
   three tables: the BGP Peer Table, the BGP Received Path Attribute
   Table, and the BGP-4 Received Path Attribute Table.  The BGP Peer
   Table contains information about state and current activity of
   connections with the BGP peers.  The BGP Received Path Attribute
   Table contains path attributes received from all peers running BGP
   version 3 or less.  The BGP-4 Received Path Attribute Table contains
   path attributes received from all BGP-4 peers.  The actual attributes
   used in determining a route are a subset of the received attribute
   tables after local routing policy has been applied.
