Your AS 65001 has two eBGP connections to AS 65002, one in Dallas and one in Houston. You want AS 65002 to prefer the Dallas link for traffic destined to your network. You configure a routing policy on your Dallas router to set an attribute on routes advertised to AS 65002. Which attribute should you set, and what is a critical consideration for this attribute to work as intended?

Set AS path prepend to 50 on routes advertised to AS 65002; ensure that the prepended AS is not your own AS.

Set origin to incomplete on routes advertised to AS 65002; ensure that the origin is set to incomplete only on the Dallas router.

Set MED to 50 on routes advertised to AS 65002; ensure that the MED is compared only when the routes come from the same neighboring AS.

Set local preference to 50 on routes advertised to AS 65002; ensure that the local preference is propagated to all routers in AS 65002.

You have deployed BGP route reflectors in your AS to reduce the number of iBGP sessions. You notice that a route reflected by a route reflector is being received by the same router that originated it, causing a loop. Which attributes are used to prevent such loops in route reflection?

BGP Attributes: Concept and Operation JN0-650 Practice Questions (Page 2)

Part of the BGP domain, which makes up ~22% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–13 in this domain), expect 1–1 from this objective — we provide 26 practice questions to prepare you well beyond it.
