The plan of record is that these publicly reachable hosts will have both a local address and a global address. The global address will be derived from a prefix announced by the ISP. > Unless I have missed some essential clause in your description above, we > appear to have a failure mode, with a root cause of user neglect or user > error, in which the non-propagation requirement for unique-local prefixes > to the global routing table is likely to be violated. Stuff happens. However, one ISP making a mistake does not have to endanger the whole Internet. Any good ISP is suppose to filter routes in the FC00::/7 prefix from its own BGP announcements, and to ignore prefix in the FC00::/7 range that peer ISP might mistakenly advertise. -- 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] --------------------------------------------------------------------
