Route dampening 20 10 2000 4000 10000 is configured in BGP view, the current penalty value of route 10.10.1.0/24 is 5000, and the status is reachable. Will the route be available after 20 minutes?

As shown in the figure is an OSI routing network, the route between RTB and RTE in the figure should be _______ route.

As shown in the figure, RTA configures the address of each interface and enables dynamic NAT-PT. The configuration is as follows: Then, the IPv6 destination address of the DNS request sent by the PC in the figure is ______, and the IPv4 destination address of the DNS response returned by the DNS server is _ _____.

IS-IS can support network layer protocols such as _______.

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.
