HP-UX IPv6 Transport Administrator's Guide for TOUR 2.0 (April 2004, rev 2)

Configuration
Stateless Autoconfiguration
Chapter 3 21
Configure IPv6 interfaces and routing using one of the following
methods:
• Stateless autoconfiguration
• Manual configuration
These methods are described in the following sections.
Stateless Autoconfiguration
Addresses on IPv6 interfaces, unlike IPv4 interfaces, can be configured
without manual intervention. With stateless address autoconfiguration,
the primary interface (lanX:0) is automatically assigned a link-local IPv6
address by the system when the interface is configured (marked “up”).
This link-local IPv6 address is generated by prepending a fixed local
address prefix (fe80::) to a token derived from the MAC address. (The
address is verified to be unique.) This allows each IPv6 interface to have
at least one source address that can be used by Neighbor Discovery.
If an IPv6 router on the network advertises network prefixes in router
advertisements, IPv6 derives secondary IPv6 addresses based on the
network interface identifier of the primary interface and on the network
prefixes advertised. IPv6 assigns this address to a secondary interface
for the network interface.
Refer to “Stateless Address Autoconfiguration” on page 60 in Chapter 6
of this guide, and the ifconfig(1M) man page for more information.
Configuring a Primary Interface (Required)
To configure a primary interface, edit the IPV6_INTERFACE[0] statement
in the /etc/rc.config.d/netconf-ipv6 file to specify the interface
name, such as lan0. The interface name must be the name of the physical
interface card, as reported by lanscan.
A sample netconf-ipv6 file entry is as follows:
IPV6_INTERFACE[0]="lan0"
IPV6_INTERFACE_STATE[0]="up"
