2 | Options for the ipv6 module are supplied as parameters at load time. | ||
3 | |||
4 | Module options may be given as command line arguments to the insmod | ||
5 | or modprobe command, but are usually specified in either the | ||
6 | /etc/modules.conf or /etc/modprobe.conf configuration file, or in a | ||
7 | distro-specific configuration file. | ||

9 | The available ipv6 module parameters are listed below. If a parameter | ||
10 | is not specified the default value is used. | ||

18 | has a dependency on the IPv6 module being loaded, but no | ||
19 | IPv6 addresses or operations are desired. | ||

31 | No IPv6 addresses will be added to interfaces, and | ||
32 | it will not be possible to open an IPv6 socket. | ||
33 | |||
34 | A reboot is required to enable IPv6. | ||
