The networking is as shown in the figure, eBGP runs between AS 100, AS 200, and AS 300, and the ATM link between RTC and RTA, RTC and RTB is connected, and ATM OAM is not enabled. If the ATM link between RTC and RTA is interrupted, RTC How long does it take for routes on AS 100 to switch over to the ATM link between RTC and RTB?

• A.Between 20s-30s

In the topology shown in the figure, by executing the import-route direct command on the RTA, 192.168.0.0/24 , 192.168.1.0/24 , 192.168.2.0/24 , 192.168.3.0/24 and 192.168.4.0/24 are injected. There are five routes. Now it is required that the above routes cannot be learned on the RTB. What configurations can be performed on the RTA?
