The ip6_setup utility displays the configuration
information and asks you to indicate whether you want to update the current
startup procedures with the new configuration information.
If you are not satisfied with the configuration, enter n.
The utility ends immediately without changing any of the current configuration
files.
If you are satisified with the configuration, enter y.
The ip6_setup utility updates the /etc/inetd.conf, /etc/rc.config, and /etc/routes files with the IPv6 configuration information. The /etc/rc.config, /etc/routes, and /etc/ip6rtrd.conf files contain configuration information used by the system startup
scripts to start IPv6. You can edit them to change your configuration.
