YANG Data Model for the OSPF Protocol YANG Data Model for the OSPF Protocol
Abstract Abstract
This document defines a YANG data model that can be used to configure This document defines a YANG data model that can be used to configure
and manage OSPF. The model is based on YANG 1.1 as defined in RFC and manage OSPF. The model is based on YANG 1.1 as defined in RFC
7950 and conforms to the Network Management Datastore Architecture 7950 and conforms to the Network Management Datastore Architecture
(NMDA) as described in RFC 8342. (NMDA) as described in RFC 8342.
