JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2022) — Question 42

Which two statements are true about what a route reflector does by default when distributing routes it has received from reflector clients? (Choose two.)

Answer options

• A. It does not change any received BGP attributes.
• B. It changes the default BGP attributes to inform peers that it is a route reflector.
• C. It sets the next hop of all routes to "self" to prevent routing loops.
• D. It adds its cluster ID to the client-received routes.

Correct answer: A, D

Explanation

The correct answers are A and D because a route reflector does not alter the BGP attributes it receives from clients, maintaining their original values, and it also attaches its cluster ID to the routes for proper identification. Options B and C are incorrect; the route reflector does not change attributes to indicate its role, nor does it set the next hop to 'self' as this is not a standard behavior of route reflectors.
