Follow these steps to configure an IPv6 unicast address:

is required.
By default, no site-local
address or aggregatable
global unicast address is
configured for an interface.
Automatically

Configure an
IPv6 link-local
address
Manually assign a

the interface
ipv6 address ipv6-address
link-local
Optional
By default, after an IPv6
site-local address or
aggregatable global unicast
address is configured for an
interface, a link-local address
will be generated
automatically.
z An interface can have only one link-local address, but can have multiple global unicast addresses
with different prefixes and site-local addresses.
z After an IPv6 site-local address or aggregatable global unicast address is configured for an
interface, a link-local address is generated automatically. The automatically generated link-local
address is the same as the one generated by using the ipv6 address auto link-local command. If
a link-local address is manually assigned to an interface, this manual link-local address takes
effect. If the manually assigned link-local address is removed, the automatically generated
link-local address takes effect.
z Manual assignment takes precedence over automatic generation. That is, if you first adopt
automatic generation and then manual assignment, the manually assigned link-local address will
overwrite the automatically generated one. If you first adopt manual assignment and then
automatic generation, the automatically generated link-local address will not take effect and the
link-local address of an interface is still the manually assigned one. If you delete the manually
assigned address, the automatically generated link-local address is validated.
