Abstract

   This document analyzes enterprise renumbering events and describes
   the best current practice among the existing renumbering mechanisms.
   According to the different stages of renumbering events,
   considerations and best current practices are described in three
   categories: during network design, for preparation of renumbering,
   and during a renumbering operation.

1. Introduction

   IPv6 site renumbering is considered difficult. Network managers might
   prefer to use Provider Independent (PI) addressing for IPv6 to
   attempt to minimize the need for future renumbering. However,
   widespread use of PI might create very serious BGP4 scaling
   problems  and PI space is not always available for enterprises
   according to the RIR (Regional Internet Registry) policies. It is
   thus desirable to develop mechanisms and practice guidelines that
   could make renumbering a simpler process to reduce demand for IPv6 PI
   spaces.

   This document undertakes scenario descriptions, including
   documentation of current capabilities and existing BCPs, for
   enterprise networks. It takes [RFC5887] and other relevant documents
