Hi,

> I believe that an extra 32-bit field in the IPv6 header could have provided a significant step towards solving this problem by encoding the destination transit AS in the packet at the first router capable of resolving that information and then routing on that basis in the IDR realm. In that case, stub networks (non-transit autonomous systems) would not need to be visible in BGP and we would not need to track prefix state beyond the closest transit ASNs. A separate map of Prefix->Candidate Transit ASNs could be maintained through a mechanism somewhat similar to DNS.

So you're in the LISP "we noticed that route caches do not scale, but we
try again and again" camp now?
