In the topology shown in the figure, by executing the import-route direct command on the RTA, inject 192.168.0.0/24 , 192.168.1.0/24 ,
The five routes 192.168.2.0/24, 192.168.3.0/24 and 192.168.4.0/24 are now required to be prohibited from learning the above routes by RTB. What configuration can be performed on RTA?

The RIP protocol is enabled on a router, the process number is 1, and the priority is 10; at the same time, the OSPF protocol is enabled, the process number is 100, and the priority is 100. If two processes learn the route of network segment 10.0.0.0/8 at the same time, the metric values ​​are 1 (hop count) and 100 (cost value) respectively, and the next hops are 1.0.0.1 and 1.0.0.2 respectively.
After the router receives the packet with the destination address 10.0.0.1, what should it do?

Among the following routing protocols, the one belonging to the IGP is ______, and the one using the path vector algorithm is ______.
