H12-831_V1.0 · Question #249
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS, and the area number is 49.0001. R3 and R6 run IS-IS, and the area number is 49.0002. Inside AS65000, R1, R3, R4, and R6 all…
The correct answer is A. For 192.168.1.0/24, the Originator_ID attribute carried by R2's preferred BGP route is 10.0.1.1 B. For 192.168.1.0/24, the Originator_ID attribute carried by R6's preferred BGP route is 10.0.1.1 C. For 192.168.1.0/24, R5 prefers the route received from R1. See the full explanation below for the reasoning.
Question
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS, and the area number is 49.0001. R3 and R6 run IS-IS, and the area number is 49.0002. Inside AS65000, R1, R3, R4, and R6 all establish IBGP neighbor relationships with R2 and R5, of which R2 and R5 are RRs and R1, R4, R3, and R6 are clients. IBGP neighbor relationships are all established using the Loopback0 interface. The IP address of the Loopback0 interface of each device is 10.0.X.X/32, and the Router ID is 10.0.XX, where X is the device number. R1 and R4 introduce the external network 192.168.1.0/24 into BGP through the import method, and R3 and R6 introduce the external network 192.168.2.0/24 into BGP through the import method. By default, which of the following descriptions are correct? (Multiple choice)
Options
- AFor 192.168.1.0/24, the Originator_ID attribute carried by R2's preferred BGP route is 10.0.1.1
- BFor 192.168.1.0/24, the Originator_ID attribute carried by R6's preferred BGP route is 10.0.1.1
- CFor 192.168.1.0/24, R5 prefers the route received from R1
- DFor 192.168.1.0/24, the Originator_ID attribute carried by R3's preferred BGP route is 10.0.2.2
