 ====== Basic IPv6 setup ======
-===== Activate IPv6 =====
+===== Installing IPv6 subsystems =====
-In order to activate basic IPv6 functionalities, you first have to enable it (disabled by default).
+First of all, we must install IRIX subsystems (they are not installed by default). The ipv6 product includes these subsystems:
+<file>
+       eoe.sw.ipv6                   kernel resident IPv6 protocol
+                                     stack, IPv6 specific user
+                                     commands, system daemons and
+                                     configuration files
+       eoe.man.ipv6                  Irix man pages for IPv6
+                                     specific commands
+       eoe.man.ipv6_rn               Irix release notes for IPv6
+                                     (this document)
+</file>
+Approximate sizes of these subsystems are as follows:
+<file>
+       Subsystem Name                Subsystem Size
+                                     (512-byte blocks)
+       eoe.sw.ipv6                           1306
+       eoe.man.ipv6                            61
+       eoe.man.ipv6_rn                         19
+</file>
+The IRIX release notes give some details for the installation.
+<file>
+       All of the subsystems for ipv6 can be installed using IRIX.
+       You do not need to use the miniroot. Refer to the IRIS
+       Software Installation Guide for complete installation
+       instructions.
+       If you are installing this product for the first time, the
+       subsystems above are not marked for installation by default
+       in the eoe base product. You must explicitly mark them for
+       installation. If upgrading a system that already has the
+       ipv6 subsystems installed, an "install upgrade" will pick
+       them up along with any other subsystems that normally would
+       be upgraded, provided the versions to be installed are
+       newer.
+</file>
+The steps are basically : open IRIX overlays with ''inst'' and then install these packages.
+You can also do this with the ''Software Manager''. Just expand ''IRIX Execution Environment'' and select ''IP Version 6 Networking''.
+===== Enabling IPv6 =====
+In order to activate basic IPv6 functionalities, you first have to enable it (disabled by default). The IRIX release notes says:
+<file>
+       A tunable flag is used to enable IPv6 on the system. This is
+       set off by default when the product is initially installed.
+       The value of the flag ip6_enable can be changed using the
+       systune utility. Set this value to 1 to enable IPv6. No IPv6
+       traffic will be passed by the kernel if this flag is set to
+. A reboot is necessary for the tunable to take effect.
+       Additional tunables for IPv6 forwarding and IPv6 automatic
+       and configured tunnelling can be found in the
+       /var/sysgen/mtune/bsd file. These features are turned off by
+       default.
+</file>
+So let's enable it:
 <code bash>
 mattieu@IRIS: ~ $ sudo systune ip6_enable 1

 reboot the system

-Then you have to reboot the system as it was asked.
+Then you have to reboot the system as it was asked. After that, everything should work since stateless autoconfig is enabled by default with IPv6.
