MVC3 Routing question

I just started to use the routes in MVC3 and I am totally confused. I hope I can get some advice on how I can do what I need from this site. Here is what I would like to do. First and most important I need all these links to go to the Product controller.

www.xx.com/product 12 code/         >> Action: Overview,  
                                    >> ProdId=12 passed as a param

www.xx.com/product 12 code/Overview >> Action: Overview,  
                                    >> ProdId=12 passed as a param

www.xx.com/product 12 code/Results  >> Action: Results,  
                                    >> ProdId=12 passed as a param

www.xx.com/product 12 code/Product  >> Action: Product, 
                                    >> ProdId=12 passed as a param
                                    >> Code=""   passed as a param

www.xx.com/product 12 code/Product/123 >> Action: Index, 
                                    >> ProdId=12 passed as a param
                                    >> Code= 123 passed as a param

What I learned already is that I can get the "12" like this:

routes.MapRoute("Route 1", // Route name
                "product {prodId} code/{action}/{id}",
                new 
                { 
                    controller = "Product", 
  开发者_如何转开发                  action = "Index", 
                    id = UrlParameter.Optional 
                }
            );

But how can I make it go to the different action events and pass the prodId and id as parameters? I think the route system is very powerful but complicated for a new user like me. How many routes do I need to set up to do what I need?

routes.MapRoute("Route 1", // Route name
                "product {prodId}/{action}/{code}",
                new 
                { 
                    controller = "Product",   //default controller=Product
                    action = "Index",         //default action= Index
                    prodId = 12,              //default prodId=12
                    code=UrlParameter.Optional // code is optional
                }
            );
