Your company has several branch offices. The branch offices are connected to the main office through private WAN links. Network traffic is routed through a server at the main office that runs Windows Server 2003 with the Routing and Remote Access Service (RRAS) role installed. The network uses the Open Shortest Path First (OSPF) routing protocol.
You configure secondary demand-dial connections for each branch office, to be used only in the event of a WAN link failure. Network monitoring reports indicate that the demand-dial connections are being used when the WAN links are available. You need to ensure that demand-dial connections are used only when the WAN links are unavailable.
