                Network Configuration Protocol (NETCONF)

Abstract

   The Network Configuration Protocol (NETCONF) defined in this document
   provides mechanisms to install, manipulate, and delete the
   configuration of network devices.  It uses an Extensible Markup
   Language (XML)-based data encoding for the configuration data as well
   as the protocol messages.  The NETCONF protocol operations are
   realized as remote procedure calls (RPCs).  This document obsoletes
   RFC 4741.
