問題2
In the network shown in the figure, R1, R2, R4, and R5 run IS-IS in area 49.0001. R3 and R6 run IS-IS in area 49.0002. Configure "import-route isis level-2 into level-1" on R2 and R5. Inside AS65000, R1, R3, R4, and R6 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.X.X, where X is the device number. R1 and R4 import the external network 192.168.1.0/24 into BGP, and R3 and R6 import the external network
192.168.2.0/24 into BGP.
Which of the following descriptions are correct by default? (Multiple choice)

問題3
In the OSPFV3 network shown in the figure, OSPFv3 is enabled on the interconnected ports of R1, R2, and R3, and IPv6 global unicast addresses are configured. R1 and R3 are DRs, so both R1 and R3 will generate Intra Area-Prefix-LSA.
