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 switch 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 one of the following methods.
Associate a neighbor IPv6 address and link-layer address with the Layer 3 interface of the local

node.
 Associate a neighbor IPv6 address and link-layer address with a port in a VLAN containing the
local node.
Follow these steps to configure a static neighbor entry:
To do...
Enter system view
Configure a static
neighbor entry
CAUTION:
You can use either method above to configure a static neighbor entry for a VLAN interface.

After a static neighbor entry is configured by using the first method, the switch needs to resolve the
corresponding Layer 2 port information of the VLAN interface.

If you use the second method, ensure that the corresponding VLAN interface exists and that the Layer 2 port
specified by
configured, the switch associates the VLAN interface with the IPv6 address to identify the static neighbor entry
uniquely.
Configuring the maximum number of neighbors dynamically
learned
The switch can dynamically acquire the link-layer address of a neighboring node through NS and NA
messages and add it into the neighbor table. A large table may reduce the forwarding performance of
the switch. You can restrict the size of the neighbor table by setting the maximum number of neighbors
that an interface can dynamically learn. When the number of dynamically learned neighbors reaches the
threshold, the interface will stop learning neighbor information.
Follow these steps to configure the maximum number of neighbors dynamically learned:
Use the command...
ipv6 address ipv6-address/prefix-
length anycast
Use the command...
system-view
ipv6 neighbor ipv6-address mac-address { vlan-id port-
type port-number | interface interface-type interface-
number }
port-type port-number
belongs to the VLAN specified by
vlan-id
125
Remarks
Optional
By default, no IPv6 anycast
address is configured on an
interface.
