=  IPv6 configuration Solaris  =

==  How can enable IPv6 autoconfiguration on particular interface?  ==

To create autoconfigured IPv6 addresses for any additional interfaces on the host that were not configured during installat
ion enter the following:
{{{
 touch /etc/hostname6.interface
}}}
Then you have to reboot to system in order to all the necessary configuration take place.

==  How can configure static IPv6 address to a particular interface?  ==

To configure static IPv6 address for a particular interface you have the enter in {{{/etc/hostname6.interface}}}
{{{
 addif 2001:db8:1:2::55/64 up
}}}


==  How can I configure static and autoconfigure IPv6 addresses to the same interface?  ==

You cannot. But you can emulate this behaviour with logical interfaces. Enabling autoconfiguration on {{{interface}}} and configure static address on {{{interface:1}}}.

==  How can I enforce an Interface ID token for autoconfiguration?  ==

You can set the IPv6 token of an  interface  to  be  used  for address autoconfiguration with the following command:
{{{
 ifconfig interface inet6 token ::last_64_bit_for_token/64
}}}
==  How can I enable Privacy Enhanced Address on Solaris?  ==

Edit the {{{/etc/inet/ndpd.conf}}} file to turn on temporary address generation.

To configure temporary addresses on all interfaces of a host, add the following to {{{/etc/inet/ndpd.conf}}}:
{{{
 ifdefault TmpAddrsEnabled true
}}}
To configure a temporary address for a specific interface, add the following to {{{/etc/inet/ndpd.conf}}}:
{{{
 if interface TmpAddrsEnabled true
}}}
Optionally in {{{/etc/inet/ndpd.conf}}} you can

 * specify valid lifetime for the temporary address.
 {{{ifdefault TmpValidLifetime duration}}}
 * specify a preferred lifetime for the temporary address, after which the address is deprecated.
 {{{if interface TmpPreferredLifetime duration}}}
 * specify the lead time in advance of address deprecation, during which the host should generate a new temporary address.
 {{{ifdefault TmpRegenAdvance duration}}}


==  How can modify IPv6 default address selection rules?  ==

You can do it in Solaris 10 and later of {{{ipaddrsel}}} command.

===  How can I review the current IPv6 default address selection table?  ===

Review the current IPv6 address selection policy table with {{{ipaddrsel}}} without any argument.
{{{
 # ipaddrsel
 # Prefix                  Precedence Label
 ::1/128                           50 Loopback
 ::/0                              40 Default
 2002::/16                         30 6to4
 ::/96                             20 IPv4_Compatible
 ::ffff:0.0.0.0/96                 10 IPv4
}}}
===  How can I add new IPv6 default address selection rules?  ===

Modify {{{/etc/inet/addrsel.conf}}} according to your needs and load it with
{{{
 ipaddrsel -f /etc/inet/ipaddrsel.conf
}}}
command

===  How can I reload the factory default IPv6 default address slection rules?  ===

If the modified policy table has problems, restore the default IPv6 address selection policy table.
{{{
 # ipaddrsel -d
}}}

===  How can prefer IPv4 addresses over IPv6 addresses?  ===

Use
{{{
 ::1/128                           50 Loopback
 ::/0                              40 Default
 2002::/16                         30 6to4
 ::/96                             20 IPv4_Compatible
 ::ffff:0.0.0.0/96                 100 IPv4
}}}
policy table.

=  How can I enable IPv6 adddress resolution on Solaris?  =
For Solaris youhave to enable separately the name resolution for IPv6:

Putting ipv4/ipv6 addresses in
{{{
 /etc/inet/ipnodes
}}}
and {{{/etc/nsswitch.conf}}}
Make sure 'ipnodes' line contains 'dns' entry so that IPv6 hostname lookup can be performed through DNS in case that resolution failed by looking up a local file.
{{{
 /etc/nsswitch.conf
 hosts:      files dns
 ipnodes:   files dns
}}}
