How to get the Controller Reference Syntax to work?

I have an issue with the Controller Reference Syntax and how to get it to work at all.

My routes.axd looks like this:

routes.MapRoute(null, "{action}", 
    new { controller = @"Home", action = @"Index" }, 
    new { action = @"Index" }, 
    new[] { "mvcApp.Controllers" });

routes.MapRoute(null, "Sites/Site1/Home/{action}", 
    new { controller = @"Home", action = @"Index" }, 
    new { action = @"Index|Other" }, 
    new[] { "mvcApp.Controllers.Sites.Site1" });

routes.MapRoute(null, "Sites/Site1/Profile/{action}", 
    new { controller = @"Profile", action = @"Index" }, 
    new { action = @"Index" }, 
    new[] { "mvcApp.Controllers.Sites.Site1" });

Now if I go to (using IIS) http://site1.localhost/home I get to the correct controller and all is fine. However if I have lets say a menu on my _Layout.cshtml looking like this:

<ul id="menu">
      <li>@Html.ActionLink("Home", "Index", "Home")</li>
      <li>@Html.ActionLink("Profile", "Index", "Profile")</li>
</ul>

the Home link routes to http://site1.localhost/Sites/Site1/Home which is the correct url. However http://site1.localhost/Home links to same place and that's what I want the ActionLink to route to. But I cannot get the syntax to work at all with for instance

<li>@Html.ActionLink("Home", "Index", "..Home")</li>

How would I get the link to route to http://site1.localhost/Home instead of http://site1.localhost/Sites/Site1/Home using the Controller reference syntax?
