          Traffic Engineering Link Management Information Base

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.

Abstract

   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 TE links as
   described in the Link Bundling in MPLS Traffic Engineering (TE)
   document.

1.  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 [RFC3410].

   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 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

2.  Introduction

   OSPF [RFC3630], Generalized MPLS (GMPLS) [RFC3471], and the Link
   Management Protocol (LMP) [RFC4204] use the concept of traffic
   engineering (TE) links to abstract link properties.  The effect of
   this approach is a reduction in the amount of routing information
   exchanged in the network, which improves routing scalability.  In
   addition, the use of TE links allows the implementation of new
