[Sysname-Vlan-interface100] ipv6 address auto

ipv6 address auto link-local

Syntax

undo ipv6 address auto link-local
View

Default level
2: System level
Parameters
None
Description
Use ipv6 address auto link-local to automatically generate a link-local address for an interface.
Use undo ipv6 address auto link-local to remove the automatically generated link-local address for the
interface.
By default, no link-local address is configured on an interface, and a link-local address will be
automatically generated after a global IPv6 unicast address is configured for the interface.
After an IPv6 global unicast address is configured for an interface, a link-local address is generated
automatically. The automatically generated link-local address is the same as the one generated by
using the ipv6 address auto link-local command.
The undo ipv6 address auto link-local command can only remove the link-local addresses
generated through the ipv6 address auto link-local command. After the undo ipv6 address auto
link-local command is used on an interface that has an IPv6 global unicast address configured, the
interface still has a link-local address. If the interface has no IPv6 global unicast address configured,
it will have no link-local address.
Manual assignment takes precedence over automatic generation. If you first adopt automatic
generation and then manual assignment, the manually assigned link-local address will overwrite
the automatically generated address. 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 of an interface is still the manually assigned address. If you delete the manually assigned
address, the automatically generated link-local address is validated. For more information about
manual assignment of an IPv6 link-local address, see the ipv6 address link-local command.
