In the topology shown in the figure, perform the following configuration in RTA and RTB respectively:
RTA-ospf-1-area-0.0.0.1]network 192.168.0.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.1.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.2.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.3.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.4.0 0.0.0.255
RTB] acl number 2000
RTB-acl-basic-2000] rule 0 permit source 192.168.0.0 0.0.0.255
RTB-acl-basic-2000] rule 5 permit source 192.168.1.0 0.0.0.255
RTB-ospf-1] filter-polic2000 import
Then the possible routes in the RTB routing table are _____

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

______ Use the shortest path first (SPF) algorithm.

After executing the displaospf routing command on the MSR router RTA, the router output is as follows:

From the above output, you can judge ______.

In the topology shown in the figure, the correct IP addresses have been configured on RTA, RTB and RTC, and the network layer is reachable.

If OSPF neighbors need to be established between routers and routes are transmitted correctly, which of the following configurations is definitely feasible?
