http://www.team-cymru.org/Services/Bogons/bgp.html Please tell me how I can configure my router to use that feed to automatically reject any bogon advertisements I receive from other BGP neigbhors.
you actually have to look at that web page
If you're seeing the same page, the configs and explanations there show how to drop packets destined to bogons, not routes.
(I also want to know the answer to that question)
then read the frelling page!!! http://www.team-cymru.org/Services/Bogons/bgp-examples.html#cisco-full-v4tra... router bgp <your asn> !
