R2: similar to R1, The loopback1 address on R2. It is set to 10.1.2.1/32. Pay attention to the changes in the IP address of the corresponding port as shown in the experiment diagram. Experiment 2: based on experiment 1, add the ports connecting R1/R2 and PC to ospf area 20/30 respectively.

Pay attention to the changes in the IP address of the corresponding port as shown in the experiment diagram. Add the port connecting to PC2 to ospf area 30. 14.7 verification method Experiment 1: ZXR10_R1 # sho ip ospf neighbor // view ospf neighbor relationship establishment OSPF Router with ID (10.1.1.1) (Process ID 100) neighbor 10.1.2.1In the area 0.0.0.0via interface fei_1/1 192.168.1.2Neighbor is DRState FULL, priority 1, Cost 1 Queue count: Retransmit 0, DD 0, LS Req 0 Dead time: 00: 00: 37In Full State for 00:00:35 // FULL State indicates successful creation. Note: If a router does not manually configure a router ID, the system automatically selects one from the IP address of the current interface. The selection principle is as follows: if the router is configured with the loopback interface, the loopback interface is preferred; if there is no loopback interface, the minimum IP address of the interface is selected from the physical interface that has been UP. For this principle, you can verify it on the vro. Because the automatically elected Router ID changes with the IP address, this will interfere with the normal operation of the Protocol. Therefore, we strongly recommend that you manually specify the Router ID.
