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 modeling a
   Multiprotocol Label Switching (MPLS) [RFC3031] based traffic
   engineering.  This MIB module should be used in conjunction with the
   companion document [RFC3813] for MPLS based traffic engineering
   configuration and management.

   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 BCP 14, RFC 2119,
   reference [RFC2119].

2.  Terminology

   This document uses terminology from the MPLS architecture document
   [RFC3031] and MPLS Label Switch Router MIB [RFC3813].  Some
   frequently used terms are described next.

   An explicitly routed LSP (ERLSP) is referred to as an MPLS tunnel.
   It consists of in-segment(s) and/or out-segment(s) at the
   egress/ingress LSRs, each segment being associated with one MPLS
   interface.  These are also referred to as tunnel segments.
   Additionally, at an intermediate LSR, we model a connection as
   consisting of one or more in-segments and/or one or more out-
   segments.  The binding or interconnection between in-segments and
