 Problem Statement for the Automated Configuration of Large IP Networks
          draft-ietf-opsawg-automated-network-configuration-02

Abstract

   This memo discusses the steps required to bring a large number of
   devices into service in IP networks in an automated fashion.  The
   goal of this document is to list known solutions where they exist and
   to identify gaps that require further specifications.

Internet-Draft   Automated Configuration of IP Networks     October 2011

1.  Introduction

   Many large IP networks are being deployed that entail the
   installation of tens of thousands of new network devices.  To keep
   costs down, it is desirable to automate the establishment of such
   networks to the maximum extent possible.  This naturally raises the
   question how new devices can pick up the configuration information
   they need to operate properly in an automated fashion.  The goal of
