Hi Robert, The answer is "no," you're not running reverse-path filtering on a BGP speaker, not even in loose mode, because that's STUPID. At the very best you're tying up router resources on a very large filtering table without measurable benefit. More likely you're blackholing packets you failed to think about, like ICMPs from routers on peering lans whose route is intentionally not introduced to the Internet at large. I suppose the customers don't really need pmtud or traceroute... Regards, Bill Herrin -- William Herrin b...@herrin.us https://bill.herrin.us/
