    description
      "This module defines a common base data model for network
topology state, representing topology that either (1) is learned
or (2) results from applying topology that has been configured
per the 'ietf-network-topology' data model, mirroring the
corresponding data nodes in this data model.  It augments the
base network state data model with links to connect nodes, as
well as termination points to terminate links on nodes.

The data model mirrors 'ietf-network-topology' but contains only
read-only state data.  The data model is not needed when the
underlying implementation infrastructure supports the Network
Management Datastore Architecture (NMDA).
