Hello! I have difficulty in convincing my US colleagues that there are still some autonomous systems in the world which pay any attention to the IRR and sometimes use it for filtering. I also having some difficulty in convincing my collegaues to update the aut-num export statement. They do believe that the folloing statent export: to AS-ANY announce ANY is just enough for all circumstances. I kindly ask you to point me to any examples of autonomous systems which still cross-check periodically import-export policy. I know of at least one such AS, it is AS15645. I also ask for the references to the autonomous systems whose routing policy (strictly) require from its peers a real export policy in the IRR. Any other arguments to the IRR usage are welcome. -- Regards, Volodymyr.
