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 by the neighbor's IPv6 address and the local Layer
3 interface number. You can configure a static neighbor entry by using either of the following methods.
• Method 1—Associate a neighbor IPv6 address and link-layer address with the Layer 3 interface of
the local node.
If you use Method 1, the device automatically finds the Layer 2 port connected to the neighbor.
• Method 2—Associate a neighbor IPv6 address and link-layer address with a port in a VLAN
containing the local node.
If you use Method 2, make sure the corresponding VLAN interface exists and that the Layer 2 port
specified by port-type port-number belongs to the VLAN specified by vlan-id. The device associates
the VLAN interface with the neighbor IPv6 address to identify the static neighbor entry.
To configure a static neighbor entry:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Configure a static
neighbor entry.
ipv6 neighbor ipv6-address mac-address { vlan-id
port-type port-number | interface interface-type
interface-number } [ vpn-instance vpn-instance-name ]
By default, no static
neighbor entry exists
on the device.
Configuring the maximum number of neighbors dynamically
learned
The device 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 might reduce the forwarding performance of
the device. 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 stops learning neighbor information.
To configure the maximum number of neighbors dynamically learned:

3. Configure the maximum
number of neighbors
which can be dynamically
learned by an interface.

Optional.
By default, a Layer 2 interface does not limit the
number of neighbors dynamically learned. A
Layer 3 interface can dynamically learn a
maximum of 1024 neighbors.
