That should further increase the viability. The IETF is an engineering organization. Engineers are good at engineering, not so good at setting policy. Let's assume that the policy is driven externally, and that engineers cannot impose their preferred solution. Some will say that the sky has begun to fall, and retire in an ivory tower of gloom. The optimistic engineer, on the other hand, will take that as a challenge. Clearly, the current set-up based on BGP and "default-free" tables is not set to absorb more than a small number of PI prefixes -- maybe a few thousands, maybe a few tens of thousands, certainly not a few hundred of millions. But who says that we cannot change it? Number portability, after all, only requires a layer of indirection. We can certainly engineer that! -- Christian Huitema _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
