Pascal,
before you go at war with everyone now you have your new set of tools up and running [ :-) ] did you check if the BGP feeds provided to you are the same that would be provided to a transit/peer/customer or internal BGP routing table. Maybe some of these networks (the CH ones, not the originating network) have a valid reason to keep these deaggregated and simply because you see them in the SwiNOG router doesn't mean they are reannounced to the whole world (note that I did not check this from other locations). If anyone does want to know how to do this (filtering on the prefix boundry allocated by the RIRs) but doesn't have the info then check these links out: Rob Thomas's bogon list: http://www.cymru.com/Documents/bogon-list.html IOS Essentials (PDF): http://www.cisco.com/public/cons/isp/essentials/IOS_Essentials_2-9.pdf Dan Goldberg's NANOG 24 Routing Policy Tutorial http://www.nanog.org/mtg-0202/ppt/golding.ppt Thomas ----- Original Message ----- From: "Pascal Gloor" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, June 13, 2002 2:28 AM Subject: [swinog] Filter small networks? > I'm wondering why some of you dont filter out tiny networks like /32 and /30 > ? > > see: > http://tools.swinog.ch/wwwbin/compare-bgp?type=mask&mask=30 > and > http://tools.swinog.ch/wwwbin/compare-bgp?type=mask&mask=32 > > > regards, > Pascal > > ---------------------------------------------- > [EMAIL PROTECTED] Maillist-Archive: > http://www.mail-archive.com/swinog%40swinog.ch/ ---------------------------------------------- [EMAIL PROTECTED] Maillist-Archive: http://www.mail-archive.com/swinog%40swinog.ch/
