BGP Routing Integrity Checker and Prefix-List Filter Generation Tool

Abstract

ISPs receive requests from their customers to advertise BGP prefixes on behalf of those customers; analyzing requests to flag incorrect prefixes imposes a significant burden on ISPs, who require a tool to perform “sanity checks” on such requests. Packet Clearing House was asked to develop such a tool, and the initial implementation, released in January 2007,is now being re-engineered to add capabilities and capacity.
