Question 46
After executing the displaospf lsdb command on the MSR router RTA, the router output is as follows:
From the above output, you can judge _______.
Question 47
As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; OSPF process 200 runs between RTA, RTB, and RTD. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 on RTA and RTB to 190, and import an external route 172.16.1.0/24 into OSPF 100 on RTC. RTA is set to redistribute OSPF100 routes to OSPF200, and RTB is set to redistribute OSPF200 routes to OSPF100. After the operation is stable, suppose that the external route 172.16.1.0/24 imported on the RTC disappears suddenly.
According to the above scenario analysis, the following description is incorrect.
