collectors to correlate multiple activities with different addresses to the same node. RFC
4941 defines privacy extensions for stateless address autoconfiguration to address this
concern. RFC 4941 defines a mechanism to generate global scoped addresses with
randomized interface identifiers that change over a period of time. The interface identifiers
changing over a period of time make it more difficult for information collectors to associate
different addresses to the same node.
New ndd Tunables
The following new tunables are introduced to enable the new functionalities released in
various IPv6Upgrade bundles:
NOTE: For a detailed information on these tunables, see the help text for the ndd
command or Table 6 (page 67).
The ip6_nd_use_temp_address, ip6_nd_temp_valid_lifetime,
ip6_nd_temp_preferred_lifetime, and ip6_nd_prefer_temp_address
tunables are introduced in the B.11.31.0803 release of the IPv6Upgrade bundle. The
remaining tunables are introduced in the B.11.31.0809 release of the IPv6Upgrade
bundle.
ip6_enable_rfc4291 Enables RFC 4291 or RFC 2373. Following are
the values for the tunable:
1 The addressing architecture conforms to RFC
4291.
0 The addressing architecture conforms to RFC
2373.
The default value is 0.
ip6_mld_version Controls the MLD protocol version used by the
system. The values for this tunable are 1 and 2.
The default value is 1.
ip6_addr_sel_enable Enables or disables RFC 3484. This tunable
specifies the default address selection for IPv6.
The default value is 0.
NOTE: The IPv6Upgrade bundle sets this
tunable to 1, to enable the RFC 3484
functionality.
ip6_icmp6_extended_errors Specifies whether to report additional ICMPv6
error messages.
1 Reports additional ICMPv6 errors as specified
in RFC 4443. The unknown ICMP error
message types are sent to upper layer
