Hi, Arnaud. The design is to only watch the origin ASN, not the other
ASNs in the path. Support for doing something with the transit portion
wof the AS_PATH will be added, probably a very simple "alert if X is
in there" or "alert if Y is not in there".
As others have said it's imperfect so ideas are welcome but the goal
here is to try to keep it useful but simple.
Thanks,
Avi
