Follow these steps to configure a static neighbor entry:
To do...
Enter system view
Configure a static
neighbor entry
Caution:
You can adopt either of the two methods above to configure a static neighbor entry for
a VLAN interface.
After a static neighbor entry is configured by using the first method, the device
needs to resolve the corresponding Layer 2 port information of the VLAN interface.
If you adopt the second method to configure a static neighbor entry, you should
ensure 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 relates the VLAN interface to an IPv6
address to uniquely identify a static neighbor entry.

1.4.2 Configuring the Maximum Number of Neighbors Dynamically Learned

The device can dynamically acquire the link-layer address of a neighbor node and add
it into the neighbor table through NS and NA messages. Too large a neighbor table from
which neighbor entries can be dynamically acquired may lead to the forwarding
performance degradation of the device. Therefore, 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:
Enter system view
Enter interface view
Use the command...
system-view
ipv6 neighbor ipv6-address
mac-address { vlan-id port-type
port-number | interface interface-type
interface-number }
