Since there are ways to dynamically filter the bogons, using BGP or DNS,
Can you share the Cisco configuration snippet you recommend to dynamically FILTER bogons using BGP or DNS? Not just inserting null-routes for the bogon aggregates, but preventing the acceptance of more-specifics that transits/peers/customers have managed to sneak past someone's filters (or lack thereof), please.
(Without an offline configuration generator, I postulate that it can't be done.)
