The ip binding vpn-instance command associates an interface on a PE with a VPN instance.
The undo ip binding vpn-instance command disables the association between a VPN instance and an interface.
By default, an interface is a public network interface and is not associated with any VPN instance.
| Parameter | Description | Value |
|---|---|---|
| vpn-instance-name |
Specifies the name of the VPN instance to be associated with the interface. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
After creating a VPN instance, you must associate the PE interface connecting to the VPN with the VPN instance. Then, the interface is used as a private network interface on which a private network address and a private network routing protocol can be configured.
Prerequisites
A VPN instance has been configured using the ip vpn-instance command.
Configuration Impact
After an interface is associated with a VPN instance or an interface is disassociated from a VPN instance, the Layer 3 features on this interface, such as the IP address and routing protocol, are deleted. The Layer 3 features need to be reconfigured if required.
Precautions
Using the undo ipv4-family or undo ipv6 family command to disable the IPv4 or IPv6 address family also deletes the IPv4 or IPv6 configurations of the interfaces bound to the VPN instance.
