3. Manually specify an IPv6
link-local address for the
interface.
ipv6 address ipv6-address
link-local
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 you configure an IPv6 global unicast address for an interface, the interface automatically generates
a link-local address. 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.
Using the undo ipv6 address auto link-local command on an interface only removes the link-local
address generated by the ipv6 address auto link-local command. If the interface has an IPv6 global
unicast address, it still has a link-local address. If the interface has no IPv6 global unicast address, it has
no link-local address.

3. Configure an IPv6 anycast
address.
ipv6 address { ipv6-address

ipv6-address/prefix-length } anycast
By default, no IPv6 anycast
address is configured on an
interface.
Configuring IPv6 ND
This section describes how to configure 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 IPv6 address and the local Layer 3 interface
number of the neighbor. You can configure a static neighbor entry by using one of the following
methods:
• Method 1—Associate a neighbor's IPv6 address and link-layer address with the local Layer 3
interface.
If you use Method 1, the device automatically finds the Layer 2 port connected to the neighbor.
• Method 2—Associate a neighbor's IPv6 address and link-layer address with a local port in a
VLAN.
