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 TCP/IP-based internets.
   In particular, it defines objects for managing the Open Shortest Path
   First Routing Protocol.

1.  The SNMPv2 Network Management Framework

   The SNMPv2 Network Management Framework consists of four major
   components.  They are:

      o RFC 1441 which defines the SMI, the mechanisms used for
        describing and naming objects for the purpose of
        management.

      o STD 17, RFC 1213 defines MIB-II, the core set of managed objects
        for the Internet suite of protocols.

      o RFC 1445 which defines the administrative and other
        architectural aspects of the framework.

      o RFC 1448 which defines the protocol used for network
        access to managed objects.

   The Framework permits new objects to be defined for the purpose of
