Note IPv6 Addressing Link-Local Unicast Address MAC Address 00-15-60-7a-ad-c0 IPv6 I/F Identifier 215:60ff:fe7a:adc0 Full Link-Local Unicast Address fe80::215:60ff:fe7a:adc0/64 09-c1-8a-44-b4-9d 11c1:8aff:fe44:b49d fe80::11c1:8aff:fe44:b49d/64 00-1a-73-5a-7e-57 21a:73ff:fe5a:7e57 fe80::21a:73ff:fe5a:7e57/64 The EUI method of generating a link-local address is automatically implemented 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" 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 LinkLocal Unicast Address " on page 4-12. 3-15
