Node definitions are further used in network topologies and inventories. It represents information that is either learned and automatically populated, or information that results from applying configured netwok information configured per the ietf-network data model, mirroring the corresponding data nodes in this data model. The data model mirrors ietf-network, 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).
