• Automatic generation—The firewall 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 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.
To configure automatic generation of an IPv6 link-local address for an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the interface to
automatically generate an
IPv6 link-local address.
ipv6 address auto link-local
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.
To configure an IPv6 link-local address manually:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an IPv6
link-local address
manually.
ipv6 address ipv6-address
link-local
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.
