    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.
