Hi Fernando,<br>
<br>
> That's my point. What is the issue of they using the already owned prefixes they got from their respective RIR and if necessary request more ?<br>
<br>
We end up with a swamp in space, with grossly inefficient routing, no aggregation, coupled with low bandwidth, long latencies, anemic processors, and insufficient memory.<br>
<br>
I would like to avoid that.<br>
<br>

Tony<br>
