Multiprotocol Label Switching (MPLS) Label Switching Router (LSR) Management Information Base (MIB)

RFC 3813                      MPLS LSR MIB                     June 2004


   -  Optionally specifying segment traffic parameters.

4.1.  Summary of LSR MIB Module

   The MIB objects for performing these actions consist of the following
   tables:

   -  The interface table (mplsInterfaceTable), which is used for
      revealing the MPLS protocol on MPLS-capable interfaces.

   -  The in-segment (mplsInSegmentTable) and out-segment
      (mplsOutSegmentTable) tables, which are used for configuring LSP
      segments at an LSR.

   -  The cross-connect table (mplsXCTable), which is used to associate
      in and out segments together, in order to form a cross-connect.

   -  The label stack table (mplsLabelStackTable), which is used for
      specifying label stack operations.

   Further, the MPLS in-segment and out-segment performance tables,
   mplsInSegmentPerfTable and mplsOutSegmentPerfTable, contain the
   objects necessary to measure the performance of LSPs, and
   mplsInterfacePerfTable has objects to measure MPLS performance on a
   per-interface basis.

   These tables are described in the subsequent sections.

5.  Brief Description of MIB Module Objects

   Sections 5.1-5.2 describe objects pertaining to MPLS-capable
   interfaces of an LSR.  The objects described in Sections 5.3-5.8,
   were derived from the Incoming Label Map (ILM) and Next Hop Label
   Forwarding Entry (NHLFE) as specified in the MPLS architecture
   document [RFC 3031].  It is appropriate to note that the in-segment,
   out-segment, and cross-connect tables were modeled after similar
   tables found in [RFC 2515].

5.1.  mplsInterfaceTable

   This table represents the interfaces that are MPLS capable.  An LSR
   creates an entry in this table for every MPLS capable interface on
   that LSR.

5.2.  mplsInterfacePerfTable

   This table contains objects to measure the MPLS performance of MPLS
   capable interfaces and is an AUGMENT to mplsInterfaceTable.
