Persistent static route information is stored at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\PersistentRoutes. When the IP stack is initialized, it is entered into the route table.

Static routes entered using RRAS Administrator are stored, along with additional information, at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Interfaces\<Interface Number>\InterfaceInfo. This information is NOT entered into the route table until the RRAS router is initialized.

NOTE: See Q178993 - How to Use Static Routes with Routing and Remote Access Service.
