ipv6 neighbor (VXLAN)
Function
The ipv6 neighbor command configures a static IPv6 neighbor entry on an interface of a VXLAN network.
The undo ipv6 neighbor command deletes a static IPv6 neighbor entry configured on an interface of a VXLAN network.
By default, no static IPv6 neighbor entry is configured on an interface of a VXLAN network.

Parameters
| Parameter | Description | Value |
|---|---|---|
ipv6-address |
Specifies a destination IPv6 address. |
The value consists of 128 bits, which are classified into 8 groups. Each group contains 4 hexadecimal numbers in the format of X:X:X:X:X:X:X:X. |
mac-address |
Specifies the destination MAC address mapping the destination IP address. |
The value is in H-H-H format. An H is a hexadecimal number of 1 to 4 digits. |
vni vni-id |
Specifies a VNI ID. |
The value is an integer that ranges from 1 to 16777215. |
source-ip ipv4-address1 |
Specifies the IP address of the source VTEP. |
The value is in dotted decimal notation. |
peer-ip ipv4-address2 |
Specifies the IP address of the destination VTEP. |
The value is in dotted decimal notation. |
source-ipv6 ipv6-address1 |
Specifies the IPv6 address of the source VTEP. |
The value consists of 128 bits, which are classified into 8 groups. Each group contains 4 hexadecimal numbers in the format of X:X:X:X:X:X:X:X. |
peer-ipv6 ipv6-address2 |
Specifies the IPv6 address of the destination VTEP. |
The value consists of 128 bits, which are classified into 8 groups. Each group contains 4 hexadecimal numbers in the format of X:X:X:X:X:X:X:X. |
vid vlan-id1 |
Specifies the outer VLAN ID in the packet received by a interface. |
The value is an integer that ranges from 1 to 4094. |
cevid vlan-id2 |
Specifies the inner VLAN ID in the packet received by a interface. |
The value is an integer that ranges from 1 to 4094. |
interface interface-type interface-number.subnum |
Specifies an L2 sub-interface. |
- |
vid vlan-id3 |
Specifies the VLAN ID in the packet received by a interface. |
The value is an integer that ranges from 1 to 4094. |
interface interface-type interface-number |
Specifies an interface. |
- |
Usage Guidelines
Usage Scenario
On a VXLAN, if a Layer 3 gateway on a VXLAN is not enabled to send ND protocol packets, run the ipv6 neighbor command to configure a static IPv6 neighbor entry. To filter out invalid ND protocol packets, you can also run this command to bind the destination IPv6 addresses of these packets to nonexistent MAC addresses. To configure a static IPv6 neighbor entry for a VXLAN tunnel:
To configure static IPv6 neighbor entries on the VXLAN tunnel side, run the ipv6 neighbor ipv6-address mac-address vni vni-id { source-ip ipv4-address1 peer-ip ipv4-address2 } | { source-ipv6 ipv6-address1 peer-ipv6 ipv6-address2 } command. If the current device has an access-side L2 sub-interface added to a BD, run the ipv6 neighbor ipv6-address mac-address { vid vlan-id1 [ cevid vlan-id2 ] } interface interface-type interface-num.subnum command to configure a static IPv6 neighbor entry for the sub-interface. If the current device has an access-side interface added to a BD based a VLAN, run the ipv6 neighbor ipv6-address mac-address vid vlan-id3 interface interface-type interface-num command to configure a static IPv6 neighbor entry for the interface.
Prerequisites
The IPv6 function has been enabled on a VBDIF interface using the ipv6 enable command.
In addition, before configuring a static IPv6 neighbor entry for the VXLAN tunnel side, ensure that a VNI ID has been associated with a BD using the vxlan vni command in the BD view on a VBDIF interface.
Precautions
- If the IPv6 address or MAC address specified in the ipv6 neighbor command is incorrect, communication with this neighbor fails.
- When the VXLAN tunnel is created dynamically, the device does not support to configure a static IPv6 neighbor entry on a VXLAN tunnel-side interface by the command ipv6 neighbor ipv6-address mac-address vni vni-id { source-ip ipv4-address1 peer-ip ipv4-address2 } | { source-ipv6 ipv6-address1 peer-ipv6 ipv6-address2 }.
