TOUR Transition Release Notes (September 2004)(11i v1 and 11i v2)

Transport Optional Upgrade Release Transition Release Notes
Announcement
8
The transition patch PHNE_35351 (for HP-UX 11i v1) implements the MLD protocol specified
in RFC 2710. MLD is a protocol used by IPv6 routers to discover the presence of multicast
listeners (that is, nodes wishing to receive multicast packets) on its directly attached links. In
addition, it is used to discover the specific multicast addresses that are of interest to the
neighboring nodes. For more information, see RFC 2710, "Multicast Listener Discovery (MLD)
for IPv6".
MLD is automatically enabled when an IPv6 interface is initialized. The Management
Information Base (MIB) for MLD, based on RFC 3019, "IP Version 6 Management Information
Base for the Multicast Listener Discovery Protocol," is also supported.
FDDI Link Support This feature was introduced in TOUR 1.0.
MC/ServiceGuard Enablement This feature was introduced in TOUR 1.0.
TCP Segmentation Offload (TSO) Transport Support for TSO-Enhanced Cards and
Drivers This feature was introduced in TOUR 2.0. For more information on TSO-enhanced
cards and drivers, go to http://www.hp.com/go/softwaredepot, and search for "TSO".
IPv6 Transition Mechanisms Enhancements This feature was introduced in TOUR 2.0.
The transition patch PHNE_35351 (for HP-UX 11i v1) implements IPv6 transition
mechanism changes to the transport stack. There have been no changes to the dual-stack
mechanism, but several important changes to the tunneling mechanisms.
The following RFCs are supported:
• RFC 2473 - Packet Tunneling in IPv6
• RFC 2893 - Transition Mechanisms for IPv6 Hosts and Routers
• RFC 3056 - Connection of IPv6 Domains via IPv4 Clouds
The following IPv6 transition enhancements are included in PHNE_35351:
• Point-to-Point Tunneling with Address Assigned End Points
• HP-UX Server can be Configured as a Router in a Point-to-Point Configured Tunnel
• IP6-in-IP6 and IP-in-IP6 Support
• HP-UX Server can be Configured as a "6to4" Router
• Automatic Tunneling using IPv4-Compatible Addresses is Obsoleted
Point-to-Point Tunneling with Address Assigned End Points This feature was
introduced in TOUR 2.0.
