Note:
After an IPv6 site-local address or global unicast address is configured for an
interface, a link-local address will be generated automatically. The automatically
generated link-local address is the same as the one generated by using the ipv6
address auto link-local command. If a link-local address is manually assigned to
an interface, this link-local address takes effect. If the manually assigned link-local
address is removed, the automatically generated link-local address takes effect.
The manual assignment takes precedence over the automatic generation. That is, if
you first adopt the automatic generation and then the manual assignment, the
manually assigned link-local address will overwrite the automatically generated one.
If you first adopt the manual assignment and then the 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 one. After you delete the
manually assigned address, the automatically generated link-local address is
validated.
The undo ipv6 address auto link-local command can be used only after the ipv6
address auto link-local command is executed. However, if an IPv6 site-local
address or global unicast address is already configured for an interface, the
interface still has a link-local address because the system automatically generates
one for the interface. If no IPv6 site-local address or global unicast address is
configured, the interface has no link-local address.

1.4.1 Configuring a Static Neighbor Entry

The IPv6 address of a neighbor node can be resolved into a link-layer address
dynamically through NS and NA messages or statically through a static neighbor entry.
The device uniquely identifies a static neighbor entry according to the IPv6 address and
the layer 3 interface ID. Currently, there are two configuration methods:
Configure an IPv6 address and link-layer address for a layer 3 interface.
Configure an IPv6 address and link-layer address for a port in a VLAN.
Follow these steps to configure a static neighbor entry:
Enter system view
Configure a static
neighbor entry
To do...
system-view
ipv6 neighbor ipv6-address mac-address
{ vlan-id port-type port-number | interface
interface-type interface-number }
