       Multiprotocol Label Switching Transport Profile (MPLS-TP)
                     MIB-Based Management Overview

Abstract

   A range of Management Information Base (MIB) modules has been
   developed to help model and manage the various aspects of
   Multiprotocol Label Switching (MPLS) networks.  These MIB modules are
   defined in separate documents that focus on the specific areas of
   responsibility of the modules that they describe.

   The MPLS Transport Profile (MPLS-TP) is a profile of MPLS
   functionality specific to the construction of packet-switched
   transport networks.

   This document describes the MIB-based architecture for MPLS-TP,
   indicates the interrelationships between different existing MIB
   modules that can be leveraged for MPLS-TP network management, and
   identifies areas where additional MIB modules are required.
