Πριν απο δύο χρόνια καναμε με τον Σπύρο Παπαγεωργίου μια εργασία (
ας το πουμε as-topology detection per country - ) χρησιμοποιώντας
γνωστά και διαθέσιμα whois . H Level 3 είναι ο μεγαλύτερος πάροχος (
per # peerings) και έχει ιδιωτικό whois <br>
το οποίο κάνει peering επειδή το αντίστοιχο του RIPE-Whois-database
έχει μικρό κάτω όριο για την καταγραφή των peerings.<br>

έχεις κάποιο εργαλείο το οποίο συγκρίνει αυτό που υπάρχει στο
router με αυτό που θα έπρεπε να είναι σαν αποτέλεσμα του script
(π.χ κάποιο rancid -like )?<br>

Ναι, όπως λες όμως... δεν βοήθησε καθόλου εδώ. Τα routes που
ανακοινώνονταν διατηρούσαν το origin τους (π.χ. 3549 4788
15169) και ως εκ τούτου το RPKI δεν προστάτευσε κανέναν από
αυτούς που έχουν ενεργοποιήσει validation.
