Table Of Contents
Support for IPv6 over VLAN
The B.11.31.0809 release of IPv6 provides support for IPv6 over virtual LAN (VLAN).
For information on VLAN configuration, see VLAN Administrator's Guide at http://
www.docs.hp.com.
Ability to Disable Autoconfiguration Based on Router Advertisements
Starting with this release of IPv6, HP provides the ability to disable autoconfiguration
based on the contents of the received router advertisements using the ip6_nd_autoconf
tunable in the ndd command. The default value of the ip6_nd_autoconf tunable is
1. For information on this tunable, enter the ndd help command or the Transport
Administrator's Guide at http://www.docs.hp.com.
Support for RFC 3810 (Multicast Listener Discovery Version 2 (MLDv2))
The B.11.31.0809 release of IPv6 updates the HP-UX implementation of Multicast Listener
Discovery protocol from RFC 2710 (Multicast Listener Discovery (MLD) for IPv6) to MLD
version 2, RFC 3810. The major feature available with RFC 3810 is the support for
source filtering, which is the ability for a node to report the include or exclude list of
source addresses the node is interested or not interested in listening. HP-UX supports the
multicast listener feature in the MLDv2 protocol but does not support the multicast router
feature in the MLDv2 protocol.
Support for RFC 3376 (Internet Group Management Protocol Version 3 (IGMPv3))
The B.11.31.0809 release updates the HP-UX implementation of Internet Group
Management Protocol to IGMPv3, RFC 3376. The major feature available with RFC
3376 is the support for source filtering, which is the ability for a node to report the include
or exclude list of source addresses the node is interested or not interested in listening.
HP-UX supports the group member feature in the IGMPv3 protocol but does not support
the multicast router feature in the IGMPv3 protocol.
Support for RFC 3678 (Socket Extension to Multicast Source Filter API)
The IGMPv3 and MLDv2 protocols enable applications to specify source filters on multicast
group memberships. RFC 3678 defines new socket options and functions that enable
applications to specify the source filters to the underlying IGMPv3 and MLDv2 protocols.
Support for RFC 4941 (Privacy Extensions for Stateless Address Autoconfiguration in
IPv6)
The B.11.31.0803 version of the IPv6Upgrade bundle supports the privacy extension
to IPv6 auto-configuration feature, which is based on RFC 4941 (Privacy Extensions for
Stateless Address Autoconfiguration in IPv6).
All the IPv6 addresses of an interface formed using the stateless address autoconfiguration
mechanism have the same interface identifier generated from the IEEE identifier of the
interface. The constant interface identifier in multiple addresses enable information
