Issue in Route Origin Validation from Route Partial Visibility

In the Resource Public Key Infrastructure (RPKI), validating prefix- origin pairs using Route Origin Authorizations (ROAs) globally and performing Route Origin Validation (ROV) locally at each Autonomous System (AS) with validated ROA payloads (VRPs) can lead to inconsistent results due to partial route visibility. This document highlights how partial route visibility can turn originally non-loose ROAs into loose VRPs, outlines the causes of partial route visibility, and discusses potential solutions to mitigate the issue.
