Margaret, You should check the evolution of the size of the DFZ tables, for example at http://bgp.potaroo.net/. From my neck of the woods, I perceive a consensus on two points: that rapid growth of the number of globally routed prefixes is not a good thing; and that the major cause of growth is "site multi-homing", which translates exactly into "some companies may pay their ISPs to globally route their (global) addresses". (Attempts at traffic engineering through clever use of routing tables is probably the other cause of table growth.) The whole point of placing restrictions on the routability of the GUPI is precisely to thwart attempts to pay your way into the routing table: whatever the amount of money on the table, the ISP cannot say yes since it cannot guarantee that other ISPs will route the GUPI. -- 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] --------------------------------------------------------------------
