RFC 8346 YANG Data Model for L3 Topologies March 2018
1. Introduction
This document introduces a YANG [RFC7950] [RFC6991] data model for
Layer 3 (L3) network topologies, specifically Layer 3 Unicast. The
model allows an application to have a holistic view of the topology
of a Layer 3 network, all contained in a single conceptual YANG
datastore. The data model builds on top of, and augments, the data
model for network topologies defined in [RFC8345].
This document also shows how the model can be further refined to
cover different Layer 3 Unicast topology types. For this purpose, an
example model is introduced that covers OSPF [RFC2328]. This example
is intended purely for illustrative purpose; we expect that a
