<p>Τάσο, <br>
</p>
<p>Όπως έγραψα και πριν, πολλά prefixes είναι invalids είναι λόγο
λάθους στο prefix length, όμως ενδέχεται να καλύπτονται από less
specific με ίδιο next hop. Θα είχε ενδιαφέρον αν υπήρχε μια
ανάλυση του πόσα prefixes είναι αυτά ή/και ποιος όγκος κίνησης
(απο αυτό το 0,8%) όντως θα κοπεί ή θα δρομολογηθεί αλλού αν
κάνεις drop τα invalid. Αν έχετε (ή βρειτε) τέτοια στοιχεία θα
είχε ενδιαφέρον να τα αναφέρετε.</p>
<p>Επίσης, βρίσκω ενδιαφέρον έχει αυτό που γράφεις με την
αυτοματοποίηση, αλλά με ποιο κριτήριο θα ξεχωρίσεις τα "πραγματικά
κακά" prefixes από τα "λιγότερο κακά"; 'H είναι απλά αυτά για τα
οποία θα γκρινιάξουν οι πελάτες; IMHO παντως είναι λάθος να δώσεις
μη προσωρινή λύση σε ένα τέτοιο πρόβλημα, ο πελάτης που γκρινιάζει
θα πρέπει να πείσει τον ομότιμό του να διορθώσει το πρόβλημά του.
Εγώ θα προτιούσα μια λογική του στύλ "το ανοίγω προσωρινά αλλά το
automation μας θα το σιδερώσει σύντομα, μιλήστε (ή μιλάμε) με τον
απένταντι για να διορθώσει το μόνιμα πρόβλημα".<br>

<p>Χαιρετισμούς,<br>
