Re: large multi-site enterprises and PI prefix [Re: who gets a /32 [Re: IPV6 renumbering painless?]]

To pick just one example, here is what AS714 is sourcing:

Network Next Hop Metric LocPrf Weight Path * i17.0.0.0/9 8.21.82.85 80 110 0 65453 2914 12182 714 i * i17.0.0.0 8.21.82.85 80 110 0 65453 2914 12182 714 i ... If all active ASes did this we'd have a 400k routing table. So please no PI in IPv6, not even for large enterprises.

i don't think that's a realistic proposition unless you intend ford and wal-mart and others with big enterprise-wide ip networks to use NAT when connecting their desktops. some of these people use direct peering in addition to transit-provider-of-the-month, and that's a good model for overall internet growth and robustness. -- Paul Vixie
