Aggregation Report: Aggregation using AS prepended PATH
Report prepared at Sat, 13 Nov 2010 04:11:55 UTC+1000, using data obtained within AS0.6447
The report may include routes internal to AS0.6447, and may also include routes
that are accepted from adjacent AS's and marked "NO EXPORT". The report also
does not take into account conditions local to each origin AS in terms of policy
or traffic engineering requirements. As an aggregation guide, this report is a
very approximate guide at best.
