Note 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 The software provides host-based IPv6 features that enable the switches covered by this guide to be managed from an IPv6 management station and to operate in both IPv6 and IPv4/IPv6 network environments. The software does not include IPv6 routing, but interoperate 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 2-7
