                        OSPFv3 Autoconfiguration

Abstract

   OSPFv3 is a candidate for deployments in environments where
   autoconfiguration is a requirement.  One such environment is the IPv6
   home network where users expect to simply plug in a router and have
   it automatically use OSPFv3 for intra-domain routing.  This document
   describes the necessary mechanisms for OSPFv3 to be self-configuring.
   This document updates RFC 5340 by relaxing the HelloInterval/
   RouterDeadInterval checking during OSPFv3 adjacency formation and
   adding hysteresis to the update of self-originated Link State
   Advertisements (LSAs).

1.  Introduction

   OSPFv3 [OSPFV3] is a candidate for deployments in environments where
   autoconfiguration is a requirement.  This document describes
   extensions to OSPFv3 to enable it to operate in these environments.
   In this mode of operation, the protocol is largely unchanged from the
   base OSPFv3 protocol specification [OSPFV3].  Since the goals of
   autoconfiguration and security can be conflicting, operators and
