Use the
undo ip binding vpn-instance
command to remove the association.
By default, an interface is associated with no VPN instance; it belongs to the public network.
When configured on an interface, the
ip binding vpn-instance
command clears the IP address of the
interface. Therefore, you must re-configure the IP address of the interface after configuring the
command.
