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.
Method 2—Associate a neighbor IPv6 address and link-layer address with a port in a VLAN
•
containing the local node.
You can use either of the previous configuration methods to configure a static neighbor entry for a VLAN
interface.
After a static neighbor entry is configured by using the first method, the device must resolve the
•
corresponding Layer 2 port information of the VLAN interface.
If you use the second method, make sure that 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. After a
static neighbor entry is configured, the device associates the VLAN interface with the IPv6 address
to identify the static neighbor entry uniquely.
To configure a static neighbor entry:
Step
1. Enter system view.
2. Configure a static neighbor
entry.
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 can 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 will stop learning neighbor information.
To configure the maximum number of neighbors dynamically learned:
Step
1. Enter system view.
2. Enter interface view.
