Edit URL in Asp.net MVC

You have 2 different issues here. First of all, it won't work right to make 3 optional parameters on a route. Only the last (right most) parameter can be optional. So, you need two routes to enable all of the combinations of 0, 1, 2, 3, 4, or 5 segments in the URL.

// This will match URLs 4 or 5 segments in length such as:
//
//   /Home/Index/2/3
//   /Home/Index/2/3/4
//
routes.MapRoute(
    name: "4-5Segments",
    url: "{controller}/{action}/{id}/{id2}/{id3}",
    defaults: new { id3 = UrlParameter.Optional }
);

// This will match URLs 0, 1, 2, or 3 segments in length such as:
//
//   /
//   /Home
//   /Home/Index/
//   /Home/Index/2
//
routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

Secondly, your ActionLink is not matching because you have specified the route value as id1, but in your route the value is id. So, you need to change ActionLink as follows.

@Html.ActionLink("my text", "myActionName", "myControllerName", new { id = 3, id2 = 7, id3 = 2}, null)

This assumes you have correctly set up your controller:

public class myControllerNameController : Controller
{
    //
    // GET: /myActionName/

    public ActionResult myActionName(int id = 0, int id2 = 0, int id3 = 0)
    {
        return View();
    }

}
