NEW QUESTION 183
In the network as shown in the figure, OSPF 100 runs on RTA, RTB, and RTC, and RTA and RTB establish EBGP neighbor relationships with RTD respectively.
AS 200 advertises route 10.10.10.0/24 to AS 100, and sets the MED value of the route advertised to RTA to 100, and the MED value of the route advertised to RTB is 200.
The main configurations of RTA and RTB are as follows:
RTA]
bgp 100
peerRTD as-number 200
peerRTB as-number 100
ospf 100
import-route bgp cost 10
RTB]
bgp 100
peerRTD as-number 200
peerRTA as-number 100
ospf 100
import-route bgp cost 20
The user wants RTC to prefer RTA when accessing 10.10.10.0/24, but it turns out that RTC chooses RTB for data forwarding.
How should the appeal issue be resolved?

- B. MED setting problem, the MED value of RTA-RTD and RTB-RTD should be exchanged.
- C. On RTA and RTB, set the OSPF internal route priority to 110, and the OSPF external route priority to 190
