HP-UX IPv6 Transport Administrator's Guide for TOUR 2.0 (April 2004, rev 2)

Features Overview
IPv6 Transport (bundled as part of TOUR 2.0)
Chapter 16
— HP-UX server can be configured as a “6to4” router:
Starting with TOUR 2.0, the HP-UX server can perform the role
of a router in a “6to4” configuration. Prior to TOUR 2.0, the
HP-UX server was only able to perform the role of a host in a
“6to4” configuration.
— IP6-in-IP6 and IP-in-IP6 Support: Starting with TOUR 2.0,
two additional tunneling types are supported, IP6-in-IP6 and
IP-in-IP6. IP6-in-IP6 tunnel configuration allows transmission of
IPv6 packets encapsulated in an IPv6 header. IP-in-IP6 tunnel
configuration allows transmission of IPv4 packets encapsulated
in an IPv6 header.
IP6-in-IP tunnel configuration allows transmission of IPv6
packets encapsulated in an IPv4 header. IP6-in-IP represents the
tunneling scenario where isolated IPv6 domains are
communicating across IPv4 networks. IP6-in-IP tunneling is not
new in TOUR 2.0, it has been supported in base (default) HP-UX
11i v2.
— Automatic Tunneling using IPv4-compatible addresses is
no longer supported: Automatic Tunneling using the special
IPv6 address type known as “IPv4-compatible address”, is no
longer supported with TOUR 2.0. The IETF is in the process of
deprecating this mechanism in favor of the generic automatic
tunneling mechanism known as “6to4.”
HP-UX 11i v2 IPv6 Transport Features Available since
HP-UX 11i v2 (not new to TOUR 2.0 release)
