[6bone] Routing artifacts after today's AS1654 problems.

[Edward Brocklesby]

Well, let's look at AS paths to a sample network, 3ffe:1400::/24.

Now, let's align these at point of origin:

Interesting? ;-) Several other netblock have the exact same as-path[1],
with the same alignment at AS33, which appears to be DEC.  Looks to me
like some more ghosted routes, but maybe someone with more experience
likes to comment?

(Sorry this mail isn't quite as thorough as the last one, but I'm really
quite knackered.  If I've missed anything vital, feel free to ask ;-)
