This architectural rigidity forces operators to apply loose, universal filters that expose networks to unauthorized route leaks and mis-originations. Italo Cunha highlights that maintaining sixteen <strong>route6 objects</strong> just to announce a <strong>/44 IPv6 prefix</strong> at <strong>/48 granularity</strong> exemplifies the unmanageable overhead plaguing current <strong>AS-set</strong> deployments.</p>
