Indicate the true statements regarding BGP routes and routing. Policy is applied first for route selection. A BGP route indicates a prefix along with its attributes. BGP route attributes include AS-PATH and NEXT-HOP. With BGP, there is exactly one unambiguous path between any source-destination pair. An autonomous system determines whether to use eBGP or IBGP to advertise routes to neighbor ASes. The AS path from source AS A to destination AS B and that from B to A must go through the same ASes. Shortest AS paths are select routes. Policy is used to break ties if there are multiple shortest AS paths. Tier-1 transit ASes know routes to all network prefixes. Multi-homed stub ASes are required to handle transit traffic. İBGP uses UDP to disseminate BGP routes to border routers within an AS. NEXT-HOP attribute is used to differentiate multiple AS-paths to a prefix. The AS-PATH attribute contains the list of ASes through which the corresponding route advertisement passed.
