Description
Use the ip binding vpn-instance command to associate an interface with a VPN instance.
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.
