The long (176) AS20912 prepend incident was due to a misconfiguration of a BGP router we were testing. The problem is that differently to Cisco the syntax of the prepend field on thius system is not a string (eg. "20912 20912 20912") but an integer, that the user interface _should_ limit to the interval 0-16. Unfortunately something has gone wrong with the syntax checker so you can enter a number (the number entered, thinking to Cisco syntax, was 20912) and the sotware interpreted it as the request of 20912 prepends... (0x51B0), dropped the highest 8 bits and processed it as the request of 0xB0=176 prepends. The producer has been warned about the problem, which I can't completely define as a "bug"... but the lack of a user configuration helper (syntax checker). I think that the case of AS47868 is the same, because I seed the modulo was involved too. Many thanks to one of our upstream providers for their support. --------------------------------------------------- Giuliano Peritore - g.peritore@panservice.it Direzione Generale - Panservice Servizi professionali per Internet ed il Networking Panservice e' associata AIIP -- RIPE Local Registry Phone: +39 0773 410020 Fax +39 0773 470219 Numero verde: 800 901492 - http://www.panservice.it ---------------------------------------------------
