Which statement describes a feature of BGP nontransitive path attributes?
- Their changes only influence the local BGP routing policy.
- They are used when the enterprise AS carries transitive data traffic.
- They are imported to an IGP when IBGP and IGP are used within an AS.
- They are advertised between autonomous systems.
Explanation: BGP path attributes (PAs) can be either transitive or nontransitive. Transitive PAs are carried from one AS to another AS and those changes could affect downstream routing for other SPs too. Nontransitive PAs influence the routing policy only within the organization. All the BGP path attributes cannot be maintained within IGP protocols. Only BGP can maintain the path attribute as the prefix is advertised from one edge of the AS to the other edge.
