  35.  
  36.    This memo defines a portion of the Management Information  Base  (MIB)
  37.    for  use  with network management protocols in TCP/IP-based internets.

  39.    Tunneling Protocol.
  40.  
  41.    This memo specifies a MIB module in a manner that is both compliant to

  61. 1.0 Introduction
  62.  
  63.    This memo defines a portion of the Management Information  Base  (MIB)
  64.    for  use  with network management protocols in the Internet Community.
  65.    In particular, it describes managed objects  used  for  managing  L2TP
  66.    hosts.
  67.  
  68. 2.0 The Network Management Framework
  69.  
  70.    The Internet-standard Network Management Framework consists of several
  71.    components.  They are:
  72.  
  73.       RFC 1902 which defines the SMI v2, the mechanisms used for
  74.           describing and naming objects for the purpose of management.
  75.  
  76.       RFC 1903  which defines textual conventions used to enhance the
  77.           clarity of object definitions.
  78.  
  79.       RFC 1156 which defines MIB-I, the core set of managed objects for
  80.           the Internet suite of protocols.  STD 17/RFC 1213 defines
  81.            MIB-II,  an  evolution  of  MIB-I  based   on   implementation
  82.       experience
  83.           and new operational requirements.
  84.  
  85.       STD 15/RFC 1157 which defines the SNMP, the protocol used for
  86.           network access to managed objects.
  87.  
  88.    The Framework permits new objects to be defined  for  the  purpose  of
  89.    experimentation and evaluation.
