The following statement is correct ________
Question 78
In the topology shown in the figure, the following configurations are performed on RTA, RTB, and RTC:
RTA-GigabitEthernet0/0] ip address 192.168.2.1 255.255.255.0
RTA-GigabitEthernet0/0] ospf network-tpe p2p
RTA] ospf 1 router-id 1.1.1.1
RTA-ospf-1] area 1
RTA-ospf-1-area-0.0.0.1] network 192.168.2.0 0.0.0.255
RTB-GigabitEthernet0/0] ip address 192.168.2.2 255.255.255.0
RTB-GigabitEthernet0/0] ospf network-tpe p2p
RTB-GigabitEthernet0/1] ip address 192.168.3.1 255.255.255.0
RTB-GigabitEthernet0/1] ospf network-tpe p2p
RTB] ospf 1 router-id 2.2.2.2
RTB-ospf-1] area 1
RTB-ospf-1-area-0.0.0.1] network 192.168.2.0 0.0.0.255
RTB-ospf-1] area 0
RTB-ospf-1-area-0.0.0.0] network 192.168.3.0 0.0.0.255
RTC-GigabitEthernet0/0] ip address 192.168.3.2 255.255.255.0
RTC-GigabitEthernet0/0] ospf network-tpe p2p
RTC] ospf 1 router-id 3.3.3.3
RTC-ospf-1] area 0
RTC-ospf-1-area-0.0.0.0] network 192.168.3.0 0.0.0.255
Then the types of LSAs generated by RTB in the OSPF area are _______
