In our survey of network operators, one commented that he must periodically verify that a backup path will be followed if a primary link fails. In the current Internet, he must unplug the link in the operational network to accomplish this. In his scenario, however, the backup path has limited capacity, and this may cause congestion for operational traffic. Shadow configurations provides a solution that does not disrupt the operational network. [DISCUSS] * To illustrate the usefulness of shadow configurations, we will give two example usage scenarios.
