정답: A,B,C,D,E

문제2

The networking is shown in the figure. RTA, RTB, RTC, and RTD are located in the same AS 100, which runs OSPF and only publishes the loopback routes of each router.

Except the OSPF COST between RTB and RTC is 15, the OSPF COST of other interconnected links is 10.
At the same time, BGP protocol is running in the network, RTD is BGP route reflector of RTA, RTB, RTC, no iBGP neighbor is established between reflector clients, RTA and RTB will be directly connected to the network segment 1.0.0.0/24 Use the network command to import into BGP. Is the following statement correct?

A. If RTC adds iBGP neighbor relationship with RTA and RTB, it may cause BGP routing loop

B. The 1.0.0.0/24 route advertised by RTB is selected on the RTC, because RTD prefers the 1.0.0.0/24 route advertised by RTB

C. Route 1.0.0.0/24 published by RTA is used on RTC, because the distance between RTA and RTC is shorter

D. If RTD is configured with BGP equivalent route, RTC will learn 1.0.0.0/24 route of RTA and RTB at the same time

정답: B
