Hi Baldur,

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.

Best regards,

Just trying to clarify the question. If you observe a BGP route to 1.2.3.0/24 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?

I would think that traceroute will have to be run directly on the same router that provides the BGP feed.

Regards 

Baldur

Hi everyone,

In the next couple of months, I want to compare data plane and control
plane measurements on a larger scale. In particular, I'm looking for
(publicly accessible) devices that receive BGP feeds and can perform a
bunch of automated (paris) traceroutes. I currently do not have an exact
probing rate or target set in mind; however, I'm sure that manually
entering IP addresses as targets for usual Looking glasses won't cut it.
Does anyone know less-restricted (maybe even automatable?) Looking
Glasses (or similar devices) or is willing to provide access to one?

BTW: I though about picking Atlas probes from ASes that feed BGP
Collector Projects (e.g. RIPE RIS or RouteViews). Unfortunately, the
respective probes are often really far apart from the feeding routers;
thus, their individual perspectives are likely misaligned :(

Best regards,

Lars
