Usage guidelines
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 has 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 overwrites the automatically
generated address. 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 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 manually assignment of an IPv6 link-local
address, see the ipv6 address link-local command.
Examples
# Configure GigabitEthernet 0/1 to automatically generate a link-local address.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] ipv6 address auto link-local
ipv6 address eui-64
Use ipv6 address eui-64 to configure an EUI-64 IPv6 address for an interface.
Use undo ipv6 address eui-64 to remove the configured EUI-64 IPv6 address for the interface.
Syntax
