I just got brief explanation from a friend in AS7514. A router in their network suddenly went out of control, and it seems this somehow generated wrong routing information. They solved the issue by disconnecting the router and are now investigating it. ----- Matsuzaki Yoshinobu <maz@iij.ad.jp> - IIJ/AS2497 INOC-DBA: 2497*629
even if customer router crash fault, should have been filtered via prefix list blocking to only allow customer network prefixs to be anounced onwards ? as per best practice colin Sent from my iPhone

Yes, I agree, and we have done that. How about peering partners - which is our case this time. Is it feasible to maintain strict inbound prefix filters for all peering relationships? ----- Matsuzaki Yoshinobu <maz@iij.ad.jp> - IIJ/AS2497 INOC-DBA: 2497*629

To be honest, not really. Some countries I know do this for their exchange points. But by-and-large, it is not scalable. Same goes for AS_PATH lists for peering. One can be liberal at peering points but have max-prefix as a basic protection mechanism (which is what we do). Of course, IRR's are the other way to go. Mark.

it does scale. We do this for all our routeservers at all exchange points we operate. In Frankfurt we have 745 peers on our routeservers.

So you have prefix and AS_PATH lists for each of the members you peer with that strictly define the prefixes they will announce to your route server?
(And: we are not a country but an exchange point operator :-)
One learns something new everyday... Mark.
Wolfgang, it's unfair ... you do not have to deal with hardware routers :). Install AS_PATH ACL and prefix list on a Cisco router (e.g. with an RSP720-3CXL) and you'll run into lots of pain ... best regards Jürgen Jaritsch Head of Network & Infrastructure ANEXIA Internetdienstleistungs GmbH Telefon: +43-5-0556-300 Telefax: +43-5-0556-500 E-Mail: jj@anexia.at Web: http://www.anexia.at Anschrift Hauptsitz Klagenfurt: Feldkirchnerstraße 140, 9020 Klagenfurt Geschäftsführer: Alexander Windbichler Firmenbuch: FN 289918a | Gerichtsstand: Klagenfurt | UID-Nummer: AT U63216601 -----Ursprüngliche Nachricht----- Von: NANOG [mailto:nanog-bounces@nanog.org] Im Auftrag von Wolfgang Tremmel Gesendet: Freitag, 17.

Scale has become my favorite term from vendors that sets off alarm bells. The problem is usually limited by someones imagination like "why would you have more than 1 comment/remark", or "what do you mean a customer has 200k prefixes registered". it all depends on who/where and what role you play. We have tried prefix filtering peers before. It's an excercise in frustration when it comes to vendors ability to ingest the large sets and/or changes. I talked about this privately and at things like IEPG. http://iepg.org/2014-03-02-ietf89/ietf89_iepg_jmauch.pdf The situation and technology haven't substantively changed in the interim. - Jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
