Transport Optional Upgrade Release (TOUR) 2.0 Release Notes
What Is in This Version
7
— 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 TOUR 1.0 (and IPv6NCF11i).
— 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 Point-to-Point Protocol (PPP) Enhancements (PPPoE and
PPPv6)
This section provides a brief summary of the PPPoE and PPPv6 features included in TOUR
2.0.
PPPoE Features
The key features of PPPoE are as follows:
• Supported over a cost-effective LAN technology, such as Ethernet.
• Conforms to RFC 2516, “A Method for Transmitting PPP Over Ethernet (PPPoE).”
In TOUR 2.0, these PPPoE features are supported on both HP-UX 11i v1 and HP-UX 11i v2.
In TOUR 1.0, they were only supported on HP-UX 11i v1.
PPPv6 Features
The key features of PPPv6 are as follows:
• PPPv6 Features: The key features of PPPv6 are as follows:
