Parameters
ipv6-address: Specifies the IPv6 address of the static neighbor entry.
mac-address: Specifies the MAC address of the static neighbor entry (48 bits long, in the format of H-H-H).
vlan-id: Specifies the VLAN ID of the static neighbor entry, in the range of 1 to 4094.
port-type port-number: Specifies a Layer 2 port of the static neighbor entry by its type and number .
interface interface-type interface-number: Specifies a Layer 3 interface of the static neighbor entry by its type and number.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN that the static neighbor entry belongs to. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the static neighbor entry is for the public network, do not specify this option.
Description
Use ipv6 neighbor to configure a static neighbor entry.
Use undo ipv6 neighbor to remove a static neighbor entry.
You can use a Layer 3 VLAN interface or a Layer 2 port in the VLAN to configure a static neighbor entry.
If the first method is used, the neighbor entry is in INCMP state. After the device obtains the corresponding Layer 2 port information, the neighbor entry will go into REACH state.
If the second method is used, the corresponding VLAN interface must 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 will relate the VLAN interface with the IPv6 address to identify the static neighbor entry uniquely and the entry will be in REACH state.
To remove a static neighbor entry, you only need to specify the corresponding VLAN interface and the neighbor address.
