問題2
A large-scale BGP network has a large number of peers. Configuring and maintaining these peers is difficult. You can add the BGP peers with the same configurations to a BGP peer group and then configure the BGP peers in batches to simplify peer management and improve route advertisement efficiency. When configuring an IBGP peer group, you do not need to specify an AS number for the peer group. When configuring an EBGP peer group, you must specify an AS number for the peer group.

On the network shown in the figure, R1 and R2 cannot establish an EBGP peer relationship through directly connected interfaces. To locate this fault, a network engineer checks BGP configurations on R1 and R2, as shown in the figure. Based on these configurations, it can be determined that the fault cause is the inconsistent router IDs and interface IP addresses.

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?

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. The import-route isis level-2 into level-1 command is configured on R2 and R5. In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are RR (Route Reflectors), and R1, R4, R3, and R6 are the iBGP peer relationship clients. The iBGP peer relationship ID is 10.0.0.X/32, where X is the number of the iBGP router.
