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 an MPLS L3VPN instance to which the static
neighbor entry belongs. The
vpn-instance-name
argument represents the VPN instance name,
a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command
configures a static neighbor entry for the public network.
Usage guidelines
A neighbor entry stores information about a link-local node. The entry can be created dynamically
through NS and NA messages, or configured statically.
The device uniquely identifies a static neighbor entry by using the neighbor's IPv6 address and the
number of the Layer 3 interface that connects to the neighbor. 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 Layer 2 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 port specified by
port-type port-number
must belong to the
VLAN specified by
vlan-id
and the corresponding VLAN interface must already exist. After
the static neighbor entry is configured, the device associates the VLAN interface with the IPv6
address to uniquely identify the static neighbor entry. The entry will be in REACH state.
You can use the
undo ipv6 neighbor
command to delete both static and dynamic neighbor
entries.
To delete a neighbor entry for a VLAN interface, specify only the corresponding VLAN interface.
Examples
# Configure a static neighbor entry for VLAN-interface 1.
