Question # 33

On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are RRs (Route Reflectors), and R1, R4, R3, and R6 are clients. The iBGP peer relationships are established using Loopback0 on each router, and the router ID is 10.0.0.X/32, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

Options:

A.

The routing table of R4 contains two equal-cost default routes.

B.

The route 192.168.1.0/24 in the routing table of R3 has two next hops.

C.

The routing table of R1 does not contain the route 192.168.2.0/24.

D.

For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.
