Abstract

   The Network Configuration Protocol (NETCONF) provides mechanisms to
   manipulate configuration datastores.  NMDA introduces additional
   datastores for systems that support more advanced processing chains
   converting configuration to operational state.  However, client
   applications are not able to be aware of common events pertaining to
   additional datstores, such as a data validation state change in
   NETCONF server, that may impact management applications.  This
   document updates [RFC6470] to allow a NETCONF client to receive
   additional notifications for some common system events pertaining to
   the Network Management Datastore Architecture (NMDA) defined in
   [RFC8342].

1.  Introduction

   The Network Configuration Protocol (NETCONF) [RFC6470] provides
   mechanisms to manipulate configuration datastores.  NMDA introduces
   additional datastores (e.g., <intended>, <operational>) for systems
   that support more advanced processing chains converting configuration
   to operational state.  However, client applications are not able to
   be aware of common events pertaining to additional datastores, e.g.,
   there are many background activities that happen during the time that
   configuration is committed to <running> to the time that the
   configuration is actually applied to <operational>.  It is possible
   that some configuration could not be applied to <operational> due to
   either validation issues, or missing resource etc.  There is a need
   for user to know the validation result of <intended> data-store and
   the reason why the configuration were not applied.

   This document updates [RFC6470] to allows a NETCONF client to receive
   additional notifications for some common system events pertaining to
   the Network Management Datastore Architecture (NMDA) defined in
   [RFC8342].  These notification are not specific to any network
   management protocols such as NETCONF and RESTCONF.

   The solution presented in this document is backwards compatible with
   [RFC6470].
