                   NETCONF Extensions to Support the
               Network Management Datastore Architecture

Abstract

   This document extends the Network Configuration Protocol (NETCONF)
   defined in RFC 6241 in order to support the Network Management
   Datastore Architecture (NMDA) defined in RFC 8342.

   This document updates RFCs 6241 and 7950.  The update to RFC 6241
   adds new <get-data> and <edit-data> operations and augments existing
   <lock>, <unlock>, and <validate> operations.  The update to RFC 7950
   requires the usage of the YANG library (described in RFC 8525) by
   NETCONF servers implementing the NMDA.

RFC 8526             NETCONF Extensions for the NMDA          March 2019

1.  Introduction

   This document extends the NETCONF protocol defined in [RFC6241] in
   order to support the Network Management Datastore Architecture (NMDA)
   defined in [RFC8342].

   This document updates [RFC6241] in order to enable NETCONF clients to
   interact with all the datastores supported by a server implementing
   the NMDA.  The update both adds new <get-data> and <edit-data>
   operations and augments existing <lock>, <unlock>, and <validate>
   operations.

   This document also updates [RFC7950] in order to enable NETCONF
   clients to both discover which datastores are supported by the
   NETCONF server and determine which modules are supported in each
   datastore.  The update requires NETCONF servers implementing the NMDA
   to support the YANG library [RFC8525].
