How to ignore current route values when generating links?

Question

Answer 1

Because r2 does not define the id parameter to be a part of the URL? If you change it to {controller}/{action}/{id}, it will be fine. You'll see the same behaviour if you change r2 to not include action: action will then also becoe a query variable.

The fact that you explicitly set it to "" means that routing will take it into account anyway. Just don't add id and you'll be fine when generating a link.
