R211x-HP Flexfabric 11900 Layer 3 - IP Services Command Reference

221
• 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.
• If Method 1 is used, the neighbor entry is in INCMP state. After the device obtains the
corresponding Layer 2 port information, the neighbor entry goes into REACH state.
• If Method 2 is used, the corresponding VLAN interface must already exist and the port specified by
port-type port-number must belong to the VLAN specified by vlan-id. After the static neighbor entry
is configured, the device associates the VLAN interface with the IPv6 address to uniquely identify
the static neighbor entry and the entry will be in REACH state.
To remove a static neighbor entry for a VLAN interface, only specify the corresponding VLAN interface.
Examples
# Configure a static neighbor entry for Layer 3 interface Ten-GigabitEthernet 1/0/1.

Usage guidelines
Perform this command to minimize link-local ND entries assigned to the driver. Link-local ND entries refer
to ND entries comprising link-local addresses.
By default, the device assigns all ND entries to the driver. With this feature enabled, the device does not
add newly learned link-local ND entries whose link local addresses are not the next hop of any route to
the driver, saving driver resources.
