Abstract
The described embodiments include a system that configures a network interface. During operation, the system receives a signal from an operating system indicating that the network interface can be idled. The signal is sent from the operating system as soon as the operating system determines that a final route structure that depended on the network interface has expired and been deleted. The system then determines if an application has established a route that uses the network interface since the signal was sent from the operating system. If not, the system causes the network interface to be idled. Otherwise, the system leaves the network interface in a current operating state.
