            Internet Key Exchange Protocol Version 2 (IKEv2)

Abstract

   This document describes version 2 of the Internet Key Exchange (IKE)
   protocol.  IKE is a component of IPsec used for performing mutual
   authentication and establishing and maintaining Security Associations
   (SAs).  This document obsoletes RFC 5996, and includes all of the
   errata for it.  It advances IKEv2 to be an Internet Standard.
