autoconf6(1Mtcp)

autoconf6 -- automatically configure IPv6 network interfaces at boot time

Synopsis

autoconf6 [-6aciMORsv] [-m main_interface] [interface ...]

Description

The autoconf6 command assigns link-local addresses to ND-capable network interfaces at boot time. It also initializes the loopback interface, automatic tunnels if required, 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.

autoconf6 understands the following options:

-6: Do not install or modify the Simple Internet Transition (SIT) interface and IPv4-compatible interoperability.
-a: Configure and bring up all acceptable interfaces.
-c: Compatibility flag for interfaces with bad link-local addresses.
-i: Configure and bring up the interfaces in the argument list.
-m interface_name: Specify the main interface, This is an alternative to specifying the main_if6 attribute to ifconfig(1Mtcp).
-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.
-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.
-v: (Verbose) Report program activity and failures.

If neither -a nor -i is specified, only currently active (up) interfaces are configured.

Notices

autoconf6 only configures Ethernet- and FDDI-like interfaces, that is, interfaces with broadcast and multicast capability, and with a 6-byte link-layer (MAC) address.

Network collisions can cause autoconf6 to fail.
