문제2

As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; RTA, RTB, and RTD run OSPF process 200. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 to 190 on RTA and RTB, and import an external route 172.16.1.0/24 to OSPF100 on RTC. The RTA is set to import the routes of OSPF100 to OSPF200, and the settings on RTB are to import the routes of OSPF200 to OSPF100 again. After the operation is stable, assume that the external route 172.16.1.0/24 imported on the RTC suddenly disappears.
According to the above scenario analysis, the following description is incorrect is ______.
