 ====== Basic IPv6 setup ====== ====== 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 
 +       0. 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> <code bash>
 mattieu@IRIS: ~ $ sudo systune ip6_enable 1 mattieu@IRIS: ~ $ sudo systune ip6_enable 1
Line 10: Line 69:
 reboot the system reboot the system
 </code> </code>
-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.
