Thanks George and sorry about the typo, our correct RTBH community is 7029:4507. If you are a Windstream BGP customer and need our material on our communities please contact your account team. Additionally, as in George's case, we found his BGP configuration was incorrect and we were not accepting /32 routes. If you experience any issue using any of our communities (no export, etc..) please open a ticket with the Windstream Enterprise Repair Center (ERC). Thanks, -Mike --Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of George Skorup Sent: Tuesday, February 02, 2016 2:16 PM To: nanog@nanog.org<mailto:nanog@nanog.org> Subject: Windstream RTBH Just wanted to follow up on this. The RTBH community is 7029:4507. After some route filter adjustments on their side (to accept a /32 advertisement from us), we're now good to go. Thanks to everyone that helped us get this sorted out.
