	The EUI method of generating a link-local address is automatically imple-
	mented on the switches covered by this guide when IPv6 is enabled on a VLAN
	interface.
	If automatically generated link-local addresses are not suitable for the
	addressing scheme you want to use, statically assigned link-local addresses
	can be used instead. (Refer to “Static Address Configuration” on page 3-9.)
	For related information, refer to:
	■ RFC 2373: “IP Version 6 Addressing Architecture”
	■ RFC 2464: “Transmission of IPv6 Packets Over Ethernet Networks”
N o t e	While only one link-local IPv6 address is allowed on an interface, multiples of
	other address types can exist on the same interface. Thus, an interface can
	have one link-local unicast address, but multiple global unicast, anycast, and
	unique local addresses.

Statically Configuring Link-Local Addresses

A link-local unicast address can be configured statically on a VLAN interface. If IPv6 is not already enabled on the VLAN, this action also enables IPv6 on the VLAN. Only one link-local address can exist on a VLAN at any time. If a link-local address (static or autoconfigured) already exists on the VLAN, then statically configuring a new one replaces the previously existing one. To statically configure a link-local address, refer to “Statically Configuring a Link- Local Unicast Address ” on page 4-12.
