HP-UX IPv6 Transport Administrator's Guide (September 2004)

Features Overview
IPv6 Transport
Chapter 1 5
— HP-UX server can be configured as a router in a
point-to-point configured tunnel: You can configure
tunneling between the following network nodes: host->router;
host->host; router-> host; and router->router. In the HP_UX 11i
v2 September 2004 release, the HP-UX server can perform the
role of the router in the tunnel configuration. Prior to HP-UX 11i
v2 September 2004 release, the HP-UX server could only perform
the host role.
— HP-UX server can be configured as a “6to4” router:
Starting with the HP-UX 11i v2 September 2004 release, the
HP-UX server can perform the role of a router in a “6to4”
configuration. Prior to the this release, 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 the HP-UX
11i v2 September 2004 release, 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 HP-UX 11i v2 September 2004 release, it is also
supported in the base (default) HP-UX 11i v2 release.
— 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 the HP-UX 11i v2 September 2004 release.
The IETF is in the process of deprecating this mechanism in
favor of the generic automatic tunneling mechanism known as
“6to4.”
