Re: Wrong /24 Announcement at UU.net / BGP IOS Bug ?
Hi ! > Hi Vinny! > > As i am thinking about this, i came to the idea that mostly uu.net applies filters > to their downstreams > e.g. there are not filtering by as - they filter by access-list > what i presume is that they use a hmmm... this could be a solution, but from what source does uunet generate this filter-list ? The Ripe-Database contains this route object: route: 126.96.36.199/16 descr: CALLISTO origin: AS6751 notify: email@example.com notify: firstname.lastname@example.org mnt-by: AS6751-MNT changed: email@example.com 19980126 source: RIPE > > access-list xyz permit 188.8.131.52 255.255.255.0 > > instead of (the correct one): > > access-list xyz permit 184.108.40.206 255.255.0.0 > > note the difference ? yes sure... but the question is, why did uunet change their filters within the last days without action from us or our customer ? And the magic is, the rest of 220.127.116.11 (e.g 18.104.22.168) is seen via 22.214.171.124/16... > > It's probably time for them to call the uunet support to fix this. > great !, 2 Tickets are already open, and no response from uunet. A company who is about to control 60% of the us-internet market can manipulate a lot of things and make a lot of money!. I would say at least 50% of the german internet isps are connected to uunet in Frankfurt. With their wrong announcement, their customers got germany traffic over a internation link and paid for this. Whom did they pay ? right uunet.... i think this wasnt a wanted effect currently but it shows what could happen and who gets money for these mistakes. I dont care this /24 in the us, because from our view it makes no difference, but for the german isps it made a big difference. We corrected it by announcing this /24 at mae-ffm, inxs and de-cix but it cant be right that we have to change our announcement because the world-leading isp has wrong filters. And calling uunet in Frankfurt leads into a 10-minute voice claiming your call is important to us... bla bla bla... i think we gonna sent all 30seconds a mail to firstname.lastname@example.org :-) hopefully their tracking systems beaks down and they are pleased to answer :-) or should we announce 126.96.36.199/24 and route it to /dev/nul... or should we dig a hole and put our uu.net problems there into ....
