NOTE:

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 can only remove 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.

Configure an IPv6 anycast address

To configure an IPv6 anycast address for an interface:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter interface view.

interface interface-type
interface-number

N/A

3.

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 firewall 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 associating a neighbor IPv6 address

and link-layer address with the Layer 3 interface of the local node.
To configure a static neighbor entry:

Step Command

1.

Enter system view.

system-view

2.

Configure a static neighbor entry.

ipv6 neighbor ipv6-address mac-address { vlan-id port-type
port-number
| interface interface-type interface-number }
