Can someone explain to me how to BYOIP into AWS and use AS prepends?
Hi Hank, I'm a bit confused by your question. Last I heard, the address blocks you bring into AWS are exclusive to AWS. If you try to use the same prefix somewhere else too, you'll end up with some black holes due to the vagaries of network routing. You'd be begging for failure. With that in mind, what are you trying to accomplish with AS prepends for AWS BYOIP? Regards, Bill Herrin -- William Herrin bill@herrin.us https://bill.herrin.us/
