    description
      "This module provides data definitions for configuration of
    Multiprotocol Label Switching (MPLS) and associated protocols for
    signaling and traffic engineering.

    RFC 3031: Multiprotocol Label Switching Architecture

    The MPLS / TE data model consists of several modules and
    submodules as shown below.  The top-level MPLS module describes
    the overall framework.  Three types of LSPs are supported:

    i) traffic-engineered (or constrained-path)

    ii) IGP-congruent (LSPs that follow the IGP path)

    iii) static LSPs which are not signaled

    The structure of each of these LSP configurations is defined in
    corresponding submodules.  Companion modules define the relevant
    configuration and operational data specific to key signaling
    protocols used in operational practice.
