       Simple VPN solution using Multi-point Security Association
                      draft-yamaya-ipsecme-mpsa-05

Abstract

   This document describes the over-lay network solution by utilizing
   dynamically established IPsec multi-point Security Association (SA)
   without individual connection.

   Multi-point SA technology provides the simplified mechanism of the
   Auto Discovery and Configuration function.  This is applicable for
   any IPsec tunnels such as IPv4 over IPv4, IPv4 over IPv6, IPv6 over
   IPv4 and IPv6 over IPv6.
