ipv6-address/prefix-length }
By default, no IPv6 global unicast
address is configured on an 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.
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.
