vulnerability, you can configure the temporary address function that enables the system to generate and
use temporary IPv6 addresses with different interface ID portions 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.
NOTE:
•
An interface can have one link-local address only. To avoid link-local address conflicts, it is
recommended to generate a link-local address on an interface automatically.
• Manual assignment takes precedence over automatic generation. If you first use automatic generation
and then manual assignment, the manually assigned link-local address will overwrite the automatically
generated one. If you first use manual assignment and then automatic generation, the automatically
generated link-local address will 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.
Follow these steps to configure automatic generation of an IPv6 link-local address for an interface:
To do... Use the command... Remarks
Enter system view system-view —
Enter interface view

—
Configure the interface to
automatically generate an
IPv6 link-local address

Optional
By default, after an IPv6 site-local
address or global unicast address is
configured on an interface, a link-local
address is generated automatically.
