Enhancing Route Origin Validation by Aggregating Validated ROA Payloads

Resource Public Key Infrastructure (RPKI) enables address space holders to issue Route Origin Authorization (ROA) objects to authorize one or more Autonomous Systems (ASes) to originate BGP routes for specific IP address prefixes. Individual BGP speakers can utilize Validated ROA Payloads (VRPs) to validate the legitimacy of BGP announcements. This document highlights potential validation errors, and recommends extension of VRPs from reasonable aggregation to enhance Route Origin Validation (ROV) and prevent validation errors that may occur due to traffic engineering or route aggregation policies.
