<p>Hi Baldur, <br>
</p>
<p>Yes, you are right. While, in general, Looking Glasses would be
optimal, those LGs that I know have rules in place that prohibit
automated requests and also limit the number of queries one can
enter manually. <br>
</p>
<p>Best regards, <br>

observe a BGP route to <a href="http://1.2.3.0/24"
moz-do-not-send="true">1.2.3.0/24</a> with AS path 1 2 3, you
want to do a traceroute to confirm that the packets indeed
travel through ASNs 1, 2 and 3?

<br>
In the next couple of months, I want to compare data plane and
control <br>
plane measurements on a larger scale. In particular, I'm
looking for <br>
(publicly accessible) devices that receive BGP feeds and can
perform a <br>
bunch of automated (paris) traceroutes. I currently do not
have an exact <br>
probing rate or target set in mind; however, I'm sure that
manually <br>
entering IP addresses as targets for usual Looking glasses
won't cut it. <br>
Does anyone know less-restricted (maybe even automatable?)
Looking <br>
Glasses (or similar devices) or is willing to provide access
to one?<br>
<br>
BTW: I though about picking Atlas probes from ASes that feed
BGP <br>
Collector Projects (e.g. RIPE RIS or RouteViews).
Unfortunately, the <br>
respective probes are often really far apart from the feeding
routers; <br>
thus, their individual perspectives are likely misaligned :(<br>
<br>
Best regards,<br>
<br>
Lars<br>
