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, Lars On 19.07.20 11:05, Baldur Norddahl wrote:
Just trying to clarify the question. If you observe a BGP route to 1.2.3.0/24 <http://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.

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
