ip binding vpn-instance

Function

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.

Format

ip binding vpn-instance vpn-instance-name

undo ip binding vpn-instance vpn-instance-name

Parameters

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 Guidelines

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

Running the undo ipv4-family or undo ipv6-family command to disable the IPv4 or IPv6 address family of a VPN instance also deletes the IPv4 or IPv6 configurations on the interface bound to the VPN instance.
Before running this command in the VE sub-interface view, ensure that the sub-interface is an L3VE sub-interface. An L3VE sub-interface has been configured using the ve-group command.

Example

# Associate GE 0/1/0 with a VPN instance named vrf1.
