<br>
I'm happy to answer this question for you. The Border 6 NSI solution<br>
performs constantly active probing via all of configured transits. Each<br>
probe is routed via the transits with "some pretty sneaky PBR/static<br>
routing". The probe configuration ensures that when it is sent via<br>
transit A it will come back via transit A, too. This allows us to know<br>
exactly what transit actually works fine, and what transit is currently<br>
misbehaving, without relying on any statistical traffic sampling. Once a<br>
transit has been flagged as 'bad', we can optionally execute an<br>
automatic action on the router to shut down the misbehaving transit.<br>
<br>
I hope this answers your question.<br>
<br>
Cheers,<br>
Pawel<br>
