IPv6 Transport (bundled as part of TOUR 1.0)
IPv6 Overview: IPv6 is the next generation Internet Protocol. The IPv6
protocol is also referred to as "IPng" (IP next generation). It provides the
infrastructure for the next wave of Internet devices, such as PDAs,
mobile phones and appliances. It also provides greater connectivity for
existing devices such as laptop computers.
IPv6 was designed by the Internet Engineering Task Force (IETF) to
improve upon the scalability, security, ease of configuration, and network
management capabilities of IPv4. HP-UX 11i IPv6 network transport
software provides host support for IPv6.
IPv6 bundled as part of TOUR 1.0: The following sections highlight IPv6
features available as part of TOUR 1.0. Some of these IPv6 features are
new for TOUR 1.0 and will be highlighted as such, the rest have been
offered since HP first made available a web release HP-UX 11i IPv6
product.
NOTE IPv6 functionality is not included in the default (base) version of HP-UX
11i. It is only available as a separate add-on product, from the web, as
part of TOUR 1.0.
HP-UX 11i IPv6 Transport Features New with
TOUR 1.0
Starting with TOUR 1.0, the following IPv6 transport features are
available:
• Host MLD Support: The host part of Multicast Listener Discovery
(MLD) protocol for IPv6 based on RFC 2710 “Multicast Listener
Discovery (MLD) for IPv6”, is supported. MLD is automatically
enabled when an IPv6 interface is initialized. The Management
Information Base for MLD, based on RFC 3019, is also supported.
RFC 2710 specifies the protocol used by an IPv6 router to discover
the presence of multicast listeners (that is, nodes wishing to receive
multicast packets) on its directly attached links, and to discover
specifically, which multicast addresses are of interest to those
