As shown in the figure, the OSPF protocol is run on the entire network, and the area 0 is summarized on R1. This summary route can be received on R2:

R2#show ip route

10.0.0.0/16 is subnetted , 1 subnets

O IA 10.1.0.0 [110/2] via 12.1.1.1 , 00:00:05 , FastEthernet0/0


71

After that, the network topology changes. As shown in the following figure, why is the summary route on R2 disappearing?
