HP-UX IPv6 Transport Administrator Guide HP-UX 11i v3 (5992-6426, May 2013)

ip_igmp_v3_unsolicited_interval Specifies the IGMPv3 unsolicited report interval.
ip_igmp_qri Specifies the IGMP query response interval.
ip_igmp_status Displays a report of the IGMP state.
ip_ipc_mcast_maxsrc Specifies the maximum source addresses in the
application filter.
ip6_ill_no_dest_unreach Disables sending of ICMPv6 destination
unreachable message.
ip6_nd_use_temp_address Controls the generation of IPv6 temporary
addresses as defined in RFC 4941.
IPv6 Transport Features Available in the Core HP-UX 11i v3 Operating System
This section describes IPv6 transport features available with the core HP-UX 11i v3
operating system.
• netstat Enhanced to Support the Display of 64-bit MIB Counters: netstat in HP-UX
11i v3 (for IPv4 and IPv6) supports the display of 64-bit MIB (Management
Information Base) counters. Thus, some of the netstat fields have the potential to
display widened output. This can cause a wraparound effect on 80-character
displays.
• IP over InfiniBand (IPoIB) Link Support: HP-UX 11i v3 provides transport support for
InfiniBand links that support IPoIB. The HP-UX 11i v3 transport software support is
required for HP InfiniBand links to run IPoIB.
The HP-UX networking utilities ifconfig, netstat, lanadmin, lanscan, arp,
rtradvd and ndp have all been enhanced to be capable of handling IPoIB-related
data. (Note that rarp has not been enhanced for handling IPoIB.)
For more information on InfiniBand and the IPoIB protocol, refer to the HP-UX
InfiniBand Support Guide available at http://www.docs.hp.com/hpux/
netcom/index.html#InfiniBand.
• Multicast Listener Discovery (MLD) Support (Host Portion Only): 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 neighboring nodes. This protocol is referred to as Multicast Listener Discovery
or MLD. MLD is derived from version 2 of IPv4’s Internet Group Management
Protocol, IGMPv2. One important difference to note is that MLD uses ICMPv6 (IP
Protocol 58) message types, rather than IGMP (IP Protocol 2) message types.
