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.
