NOTE:
•
After an IPv6 site-local address or a 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 can only remove the link-local addresses generated
through the ipv6 address auto link-local command. However, if an IPv6 site-local address or a 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.
Configure an IPv6 Anycast Address
Follow these steps to configure an IPv6 anycast address for an interface:
To do... Use the command... Remarks
Enter system view system-view —
Enter interface view
interface interface-type

—
Configure an IPv6 anycast address
ipv6 address
ipv6-address/prefix-length
anycast
Optional
By default, no IPv6 anycast
address is configured on an
interface.
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 according to the neighbor IPv6 address and the
local Layer 3 interface number. There are two configuration methods:
• Associate a neighbor IPv6 address and link-layer address with a Layer 3 interface.
• Associate a neighbor IPv6 address and link-layer address with a port in a VLAN.
Follow these steps to configure a static neighbor entry:
To do... Use the command... Remarks
Enter system view system-view —
Configure a static
neighbor entry
