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. 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?

문제5
As shown in the figure, RIR4 is one of the four routers in AS 123. They all run OSPE and realize the routing interconnection within the AS. Among them, the two network segments 10.1.1.0/24 and 10.4.4.0/24 are not published to OSPF. Now, R1 and R4 have established an IBGP peer relationship based on the Loopback0 interface, and published the network segments 10.1.1.0/24 and 10.4.4.0/24 to BGP respectively.
Which of the following methods can enable PC1 and PC2 to communicate with each other?
