3. Enable the system to
preferably use the temporary
IPv6 address as the source
address of the packet.
ipv6 prefer temporary-address
By default, the system does not
preferably use the temporary
IPv6 address as the source
address of the packet.
To generate a temporary address, an interface must be enabled with stateless address autoconfiguration.
Temporary IPv6 addresses do not overwrite public IPv6 addresses, so an interface can have multiple IPv6
addresses with the same address prefix but different interface IDs.
If an interface fails to generate a public IPv6 address because of a prefix conflict or other reasons, it does
not generate any temporary IPv6 address.
Configuring an IPv6 link-local address
Configure IPv6 link-local addresses using one of the following methods:
• 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—Manually configure an IPv6 link-local address for an interface.
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
becomes effective.

3. Configure the interface to
automatically generate an
IPv6 link-local address.
ipv6 address auto link-local
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.
