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 Generalized
   Multiprotocol Label Switching (GMPLS) [RFC3945] based traffic
   engineering (TE).  The tables and objects defined in this document
   extend those defined in the equivalent document for MPLS traffic
   engineering [RFC3812], and management of GMPLS traffic engineering is
   built on management of MPLS traffic engineering.

   The MIB modules in this document should be used in conjunction with
   the companion document [RFC4803] for GMPLS-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, [RFC2119].

1.1.  Migration Strategy

   MPLS-TE Label Switched paths (LSPs) may be modeled and managed using
   the MPLS-TE-STD-MIB module [RFC3812].

   Label Switching Routers (LSRs) may be migrated to model and manage
   their TE LSPs using the MIB modules in this document in order to
   migrate the LSRs to GMPLS support, or to take advantage of additional
   MIB objects defined in these MIB modules that are applicable to
   MPLS-TE.

   The GMPLS TE MIB module (GMPLS-TE-STD-MIB) defined in this document
   extends the MPLS-TE-STD-MIB module [RFC3812] through a series of
   augmentations and sparse augmentations of the MIB tables.  The only
