Required
By default, no IPv6 global unicast
address is configured on an interface.
NOTE:
Using the undo ipv6 address auto command on an interface removes all IPv6 global unicast addresses
automatically generated on the interface.
Configuring an IPv6 link-local address
IPv6 link-local addresses can be configured in either of the following ways:
• Automatic generation: The device automatically generates a link-local address for an interface
according to the link-local address prefix (FE80::/10) and the link-layer address of the interface.
• Manual assignment: IPv6 link-local addresses can be assigned manually.
NOTE:
•
An interface can have only one link-local address. To avoid link-local address conflicts, use the
automatic generation method.
• Manual assignment takes precedence over automatic generation. If you first use automatic generation
and then manual assignment, the manually assigned link-local address overwrites the automatically
generated one. If you first use manual assignment and then automatic generation, the automatically
generated link-local address does not take effect and the link-local address is still the manually assigned
one. If you delete the manually assigned address, the automatically generated link-local address is
validated.

Optional
By default, no link-local address is
configured on an interface.
After an IPv6 global unicast address is
configured on the interface, a link-local
address is generated automatically.
