Re: And Now for Something Completely Different (was Re: IPv6 news)

So the routing problem was looked at, and making a fundamental routing change was rejected by both the operational community and the routing folks.

No, IPv6 doesn't fix (or even change) the routing of the system, and that problem will fester until it becomes important enough to change.

From this end of the elephant, we looked at Nimrod and saw potential there, but did not buy off on it. We also looked at GSE and the routing folks at the very least seemed bought into that, but it died, under what I would characterize as a purely political hailstorm.

Yes, the lack of a scalable routing architecture will continue to fester until it has sufficient political visibility that it exceeds our pain threshold and we decide to make the change. The problem with this model is that the pain of change grows daily. Each and every v6 system that is deployed is yet another bit of installed base that will need to be updated someday.

The Internet community needs the IETF leadership to understand this very clearly and to take action to resolve this issue sooner, not later. As others have said, this is a pay now or pay later situation, and the pay later portion is MUCH more expensive. Specifically, the IAB should call for a halt to IPv6 deployment until consensus is reached on a scalable routing architecture. I realize that this is painful, but continuing to deploy is simply creating a v6 mortgage that we cannot afford to pay off.
