문제1

The illustration is a BGP multi-exit enterprise network. Which of the following statements is true about BGP deployments in multi-egress enterprise networks:

A. In mode (1), RTC can choose one of the default routes through IGP to reach the Internet according to its own strategy.

B. In a BGP multi-exit enterprise network, there can be (1) ISP only advertises default routes, (2) ISP advertises part of default routes and Internet specific routes, (3) ISP advertises all Internet routes.

C. Usually, in mode (3) RTC can choose the optimal path to access Interner through IGP according to its own strategy.

D. In mode (2), RTC can reach the Internet through part of the Internet specific routes and through the IGP protocol according to its own strategy.

문제2

According to the topology shown in the figure, the OSPF router type for RTE is ________.

A. ASBR

B. Intra-area router

C. Backbone router

정답: A,C,D

문제3

E As shown in the figure, RTB and RTC each learn EBGP route N from RTD, RTB is missing LOCAL_PREF is set to 200, IBGP neighbor relationship is established between RTA, RTB and RTC through loopback, in the RTA routing table, only N, RTB and RTC are The loopback and RTA itself are directly routed. If RTB goes down due to power failure, can route N be switched to RTC immediately on RTA?

A. No, because RTA and RTB establish IBGP neighbor relationship through loopback address. If the interconnection interface is improved, it can be switched up

B. No, because the neighbor relationship between RTA and RTB will not be interrupted until the holdtime expires, and it will take about 3 minutes to switch over.

C. Yes, because the neighbor relationship between RTA and RTB is broken, RTA immediately switches to RTC

D. Yes, because the next hop of the route N pointing to RTB is unreachable, RTA immediately switches to RTC

정답: D
