JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 16

Which origin code is preferred by BGP?

Answer options

• A. Internal
• B. External
• C. Incomplete
• D. Null

Correct answer: A

Explanation

The Internal origin code is preferred by BGP because it indicates that the route was originated within the AS. External and Incomplete are less preferred because they suggest that the route originated from outside the AS or that the origin is unknown, respectively. Null is not an origin code that conveys any routing information and therefore holds no preference in BGP.
