Introduction to IPv6
Configuration and Management
Configuration and Management
This section outlines the configurable management features supporting IPv6
operation on your ProCurve IPv6-ready switch.
Management Features
Software releases K.13.01and greater provide host-based IPv6 features that
enable the switches covered in this guide to be managed from an IPv6
management station and to operate in both IPv6 and IPv4/IPv6 network
environments.
N o t e Software releases K.13.01 and greater do not include IPv6 routing, but inter-
operate with routers that support IPv6 and IPv4/IPv6 router applications.
IPv6 Addressing
The switch offers these IPv6 address configuration features:
■ SLAAC (stateless automatic address configuration)
■ DHCPv6 (stateful automatic address configuration)
■ static address configuration
SLAAC (Stateless Automatic Address Configuration)
Enabling IPv6 on a VLAN automatically enables configuration of a link-local
unicast IPv6 address on the VLAN. (No DHCPv6 server is needed.) This
address begins with the hexadecimal prefix
fe80, which is prepended to the
interface identifier part of the address. (The interface identifier is generated
from the MAC address of the VLAN itself, using the 64-bit extended unique
identifier (EUI) method.) This enables the IPv6 nodes on the VLAN to
configure and manage the switch.
Enabling IPv6 address auto configuration on a VLAN automatically enables
automatic configuration of global unicast addresses on the VLAN. After
enabling auto configuration, a router advertisement (RA) containing an
assigned global address prefix must be received on the VLAN from an IPv6
router on the same VLAN. The resulting address is a combination of the prefix
and the interface identifier currently in use in the link-local address. Having a
global unicast address and a connection to an IPv6- aware router enables IPv6
