The goal of the recommendation is both to provide some degree of isolation, and also to ensure that the local addresses are not abused in the future. One way to achieve that is to ensure that routers systematically junk any packet sent to FC00::/8 or FD00::/8, unless a more specific route has been installed. This will not require Dan to update his internal routers, since there will indeed be a more specific route for his own internal site. Backdoor connections between links will also work, if a /48 route is announced for the backdoor. -- Christian Huitema -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
