IPv6 Interface Configuration File

IPv6 uses the /etc/hostname6.interface file at start up to automatically define IPv6 logical interfaces. When you select the IPv6 Enabled option during Oracle Solaris installation, the installation program creates an /etc/hostname6.interface file for the primary network interface, in addition to the /etc/hostname.interface file.

If more than one physical interface is detected during installation, you are prompted as to whether you want to configure these interfaces. The installation program creates IPv4 physical interface configuration files and IPv6 logical interface configuration files for each additional interface that you indicate.

As with IPv4 interfaces, you can also configure IPv6 interfaces manually, after Oracle Solaris installation. You create/etc/hostname6.interface files for the new interfaces. For instructions for manually configuring interfaces, refer to Administering Interfaces in Solaris 10 3/05 or Chapter 6, Administering Network Interfaces (Tasks).

The network interface configuration file names have the following syntax:

hostname.interface
hostname6.interface

The interface variable has the following syntax:

dev[.module[.module ...]]PPA

dev

Indicates a network interface device. The device can be a physical network interface, such as eri or qfe, or a logical interface, such as a tunnel. See IPv6 Interface Configuration File for more details.

Module

Lists one or more STREAMS modules to be pushed onto the device when the device is plumbed.

PPA

Indicates the physical point of attachment.

The syntax [.[.]] is also accepted.
