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.
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. If a link-local address is manually assigned to an interface,
this manual link-local address takes effect. If the manually assigned link-local address is removed, the
automatically generated link-local address takes effect.
The undo ipv6 address auto link-local command only removes the link-local addresses generated
through the ipv6 address auto link-local command. However, if an IPv6 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 global unicast address is configured, the interface has no
link-local address.

Configuring IPv6 ND
Configuring a static neighbor entry
The IPv6 address of a neighboring node can be resolved into a link-layer address dynamically through
NS and NA messages or through a manually configured static neighbor entry.
The device uniquely identifies a static neighbor entry by the neighbor's IPv6 address and the local Layer
3 interface number. You can configure a static neighbor entry by using either of the following methods.
• Method 1—Associate a neighbor IPv6 address and link-layer address with the Layer 3 interface of
the local node.
If you use Method 1, the device automatically finds the Layer 2 port connected to the neighbor.
• Method 2—Associate a neighbor IPv6 address and link-layer address with a port in a VLAN
containing the local node.
