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 for Traffic Engineered
   (TE) Tunnels; for example, Multi-Protocol Label Switched Paths ([7],
   [8]).  The MIB module defined by this memo allows one to configure TE
   Tunnels, to assign one or more paths to a Tunnel, and to monitor
   operational aspects of the Tunnel, such as the number of octets and
   packets that have passed through the Tunnel.

   As it stands, this MIB module can only be used to configure or
   monitor a TE Tunnel at its ingress.  The ingress is then expected to
   use some protocol (such as RSVP-TE) to signal the other routers in
   the path the information they need to set up the tunnel.  The
   extension of this module for use at other points of a Tunnel is for
   further study.

1.1.  Specification of Requirements

   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 [1].

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 [8].

   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 [2], STD 58, RFC 2579 [3] and STD 58, RFC 2580 [4].

3.  Overview of the MIB Module

   The Traffic Engineering MIB module consists of four parts:

      1) Traffic Engineering information,
      2) a table of Traffic Engineering Tunnels,
      3) a table of Paths that tunnels take, and
      4) a table of Hops that make up a tunnel path.
