autoconf6 Command

Purpose

Automatically configures IPv6 network interfaces at boot time.

Syntax

autoconf6 [-a ] [-i] [-s] [-6] [-M] [-O] [-R] [-c] [-v] [-m main_interface] [interface_name ...]

Description

The autoconf6 command is used at boot time to assign link-local addresses to ND-capable network interfaces. The autoconf6 command initializes also the loopback interface, the automatic tunnels if needed, and adds some needed routes. It can also be used at any time to set link-local addresses and automatic tunnelling on newly configured ethernet-like interfaces.

Flags

-a	Configures and turns up all the acceptable interfaces.
-i	Configures and turns up the interfaces in the argument list. Without the -a and -i flags only the interfaces already up are configured.
-m interface_name	Specifies the main interface. You can also use the no command with argument main_if6.
-s	Installs the SIT interfaces and IPv4-compatible programs. Without this flag, the SIT interfaces are configured only if an SIT interface is already up.
-6	The SIT interface and IPv4-compatible interoperability are not installed or modified.
-M	(Debug) Do not modify existing IPv6 multicast routes.
-O	(Debug) Do not configure the loopback interface.
-R	(Debug) Do not install a default IPv6 route.
-c	Old compatibility flag for those who have bad LL addresses.
-v	Verbose output. The program displays what it is doing and/or what it is failing.
interface_name	Give to the program the name of the main IEEE LAN interface.
