Re: Cymru Bogon Route Help
Can you give us a little more details around how you're trying to convert the BGP routes received into an ACL? While we're on the topic, I'd really love for the Team Cymru folks to turn their bogon list into a Flowspec feed <hint hint> ;) Sorry for the top post, I'm on my BB. Stefan Fouant ------Original Message------ From: Chris Gotstein To: nanog@nanog.org Subject: Cymru Bogon Route Help Sent: Feb 1, 2010 1:55 PM I'm in the process of trying to setup bgp peering with Cymru to receive the bogon route list. I've got everything setup using the examples they have listed, but can't get the filtering to actually work on the incoming bgp. Using a Cisco 7200 router. Any off-list help would be appreciated.

As he said, there are examples of how to implement this on the Cymru website, see: http://www.team-cymru.org/Services/Bogons/routeserver.html You're not converting anything, you're feeding prefixes from a community into a community-list that you are doing a route-map on. The route map sets a next-hop that has a static route to a null interface. Chris, I assume you are applying the route map on your peering interfaces right? I noticed that part was left out of the example assuming you were doing it yourself. Though I've been able to get this working on the 7200 before, you might want to ask cisco-nsp if you're having specific (mis?)behavior with policy routing on Cisco gear.
