NEW QUESTION 70
The networking is shown in the figure. RTB and RTC each advertise a 10.1.1.0/24 BGP route to RTA. The LP of the route advertised by RTB is set to 200, and the MED of the route advertised by RTC is set to 200.
Which BGP route should RTA prefer?
- A. RTB, because the LP of RTB routing is 200, which is greater than the LP of RTC routing.
- B. RTC, because BGP prefers routes outside the autonomous system.
- C. RTC, because the RTC route has no LP attribute, so the LP is not compared, and the MED value of RTC is 100 < the MED value of RTB is 200, so RTC routing is preferred.
- D. RTB, because BGP prefers routes inside the autonomous system.
Answer: A
