In the IS-IS network shown in the figure, RTB is configured with route aggregation.
So which of the following routes are included in the IS-IS routing table of RTC?

Which of the following statements are true about the command import-route ?

On MSR routers, the default OSPF link cost values ​​for Gigabit Ethernet, 100M Ethernet, and 10M Ethernet are respectively

Execute the following command on the MSR router RTA:
RTA-GigabitEthernet0/0]ip address 192.168.1.1 24
RTA-GigabitEthernet0/0]uit
RTA]router id 1.1.1.1
RTA]ospf 1 router-id 2.2.2.2
RTA-ospf-1]uit
RTA]interface LoopBack 0
RTA-LoopBack0]ip address 3.3.3.3 32
In the above configuration, it can be judged that the Router ID of OSPF process 1 of RTA is ______

LSAs of type ______ are definitely not injected into the OSPF TotallNSSA area.
