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.

1.  Abstract

   This memo defines a Management Information Base (MIB) for use with
   network management protocols in the Internet community.  In
   particular, it describes managed objects used for managing tunnels of
   any type over IPv4 networks.  Extension MIBs may be designed for
   managing protocol-specific objects. Likewise, extension MIBs may be
   designed for managing security-specific objects.  This MIB does not
   support tunnels over non-IPv4 networks (including IPv6 networks).
   Management of such tunnels may be supported by other MIBs.

2.  Introduction

   Over the past several years, there have been a number of "tunneling"
   protocols specified by the IETF (see [28] for an early discussion of
   the model and examples).  This document describes a Management
   Information Base (MIB) used for managing tunnels of any type over
   IPv4 networks, including GRE [16,17], IP-in-IP [18], Minimal
   Encapsulation [19], L2TP [20], PPTP [21], L2F [25], UDP (e.g., [26]),
   ATMP [22], and IPv6-in-IPv4 [27] tunnels.

   Extension MIBs may be designed for managing protocol-specific
   objects.  Likewise, extension MIBs may be designed for managing
   security-specific objects (e.g., IPSEC [24]), and traffic conditioner
   [29] objects.  Finally, this MIB does not support tunnels over non-
   IPv4 networks (including IPv6 networks).  Management of such tunnels
   may be supported by other MIBs.

3.  The SNMP Network Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o    An overall architecture, described in RFC 2571 [1].

   o    Mechanisms for describing and naming objects and events for the
        purpose of management. The first version of this Structure of
        Management Information (SMI) is called SMIv1 and described in
        STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
        second version, called SMIv2, is described in STD 58, RFC 2578
        [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7].

   o    Message protocols for transferring management information. The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [8]. A second version of the SNMP
        message protocol, which is not an Internet standards track
        protocol, is called SNMPv2c and described in RFC 1901 [9] and
        RFC 1906 [10].  The third version of the message protocol is
        called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and
        RFC 2574 [12].

   o    Protocol operations for accessing management information. The
        first set of protocol operations and associated PDU formats is
        described in STD 15, RFC 1157 [8]. A second set of protocol
        operations and associated PDU formats is described in RFC 1905
