IPv6 is enabled either during the installation procedure or by executing the following four steps:

* 1. Create an empty file by the name of "hostname." for every interface that is to support IPv6, e.g.:

# touch /etc/hostname6.hme0

* 2. Reboot
* 3. Excecute the following command for every interface that is now IPv6-enabled:

# ifconfig inet6 plumb up

This initializes the IPv6-Stack (inet6) for every interface.

Note for Solaris 9 users: We have been told that this step is no longer neccessary on the newer version of Solaris. The corresponding interfaces are automatically initialized.
* 4. At last excecute the script "/etc/init.d/inetinit". If more than one interface was enabled with IPv6 (or on Solaris 9, when the file "/etc/inet/ndpd.conf" is present) this will enable IPv6-forwarding and procedures like router advertisements and the routing protocol RIPng . If only one interface with IPv6 support is present only the neighbor discovery procedure will be started (as client). In any case this behaviour can also be changed by editing the "inetinit" script.
