     Autonomic IPv6 Edge Prefix Management in Large-scale Networks
                 draft-ietf-anima-prefix-management-00

Abstract

   This document describes an autonomic solution for IPv6 prefix
   management at the edge of large-scale ISP networks.  An important
   purpose of the document is to use it for validation of the design of
   various components of the autonomic networking infrastructure.

1.  Introduction

   This document proposes an autonomic solution for IPv6 prefix
   management in large-scale networks.  The background to Autonomic
   Networking (AN) is described in [RFC7575] and [RFC7576].  A generic
   autonomic signaling protocol (GRASP) is specified by
   [I-D.ietf-anima-grasp] and would be used by the proposed autonomic
   prefix management solution.  An important purpose of the present
