Router RT-1 and router RT-2 both advertise network 131.25.0.0/16 to router RT-3 via internal
BGP. What is the reason that router RT-3 chose router RT-1 as its best path to network
131.25.0.0/16.

A.
It advertises the best AS-path.

B.
It advertises the best origin code.

C.
It advertises the best MED.

D.
It advertises the best local preference.

E.
It has a better router ID.

F.
It advertises a lower autonomous system.

Explanation:
After BGP receives updates about different destinations from different autonomous systems, it
chooses the best path to reach a specific destination.
The following process summarizes how BGP chooses the best route on a Cisco router.
In this case, since everything else is equal the router ID will be used, and the specific router ID
that is chosen is 165.1.1.1 (lowest one), which is RT-3.
