As I understand by now, it is highly recommended to set a max-prefix limit for peering sessions. Yet, I can hardly find any recommendations on how to arrive at a sensible limit. You are missing two important questions a) should I apply it to before or after policy b) what should I do when it triggers, should I reset or stop accepting new
When I read through [1] earlier today, I had the feeling that these question rather strictly translate to: a) Do I keep rejected routes around? b) Can I traffic-wise afford dropping the session to send a strong signal to my peer? Hence, I didn't dig deeper. Best regards, Lars [1] https://tools.ietf.org/id/draft-sa-grow-maxprefix-00.html#rfc.section.3.1
