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 about 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.
