In the OSPF protocol, the correct statement about ABR aggregation is ______

In the NSAP address 06.2400.0001.0020.0300.01, which part is the Stem ID?

L is a network design engineer. In a certain network project, in order to reduce the complexity, the small L design network adopts a two-layer architecture, and the access layer functions are incorporated into the convergence layer. In the design, the small L takes into account that the core layer needs to have a fast convergence function, and the convergence layer performs route aggregation to reduce the number of routes. Among the following routing protocols, which one should be used as the core layer routing protocol?

The command to cancel the automatic route aggregation of the RIP protocol on the MSR router is ___________.

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
