What is the problem below?

    routes.MapRoute(
         "Default2", // Route name
         "{controller}/{action}/{id}", // URL with parameters
         new { controller = "Home", action = "Index", id = "test" } // Parameter defaults
     );

    routes.MapRoute(
         "Default1", // Route name
         "{controller}/{action}/{name}", // URL with parameters
         new { controller = "Home", action = "Report", name = "" } // Parameter defaults
     );

When I navigate to /home/index "id" parameter takes the default value of "test" but when I navigate to home/report the name parameter is null.

In short, if the route definition is the first in the route table, then the parameter takes its default value. But the others below don't.
