Scenario
현재 상황
A BGP edge prefers the right path while the RPKI validation state on the backup path now marks a once-valid route as notfound and blocks failover intent after a tenancy boundary redesign through a shared-services carve-out through a platform ownership split through a boundary hardening pass through an isolation boundary reset through a hardened trust reset through a trust boundary normalization through a platform trust convergence through a converged platform boundary through a trust surface consolidation through a trust contract narrowing under a segmented operator boundary during a fallback contract review during a delayed control handoff 상황에서 check backup path validation state, not only active-best-path attributes를 중심으로 원인을 좁혀가는 시나리오입니다.
