BGP Origin AS Validation

RPKI-based BGP origin AS validation is a feature that helps prevent network administrators from inadvertently advertising routes to networks they don't control. It uses a Resource Public Key Infrastructure (RPKI) server to authenticate that certain BGP prefixes originated from an expected AS before the prefixes are allowed to be advertised.
