The administrator wants to verify the current state of the OSPF database loading process. Which show command should the administrator use?()
A. show ip ospf [process - id] interfaceB. show ip ospf neighborC. show ip ospf [process - id]D. show ip ospf [process - id area - id] database
考题
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.

Issue the no ip mroute - cache privileged EXEC command.D. Issue the clear ip mroute privileged EXEC command.

OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? （）A. The ip ospf network broadcast command should be configured on each Frame Relay interfaceB. The ip ospf network non -broadcast command should be configured on each Frame Relay interfaceC. Th e ip ospf priority value on the spoke routers should be set to 0D. The ip ospf priority value on the hub router should be set to 0E. The neighbor command should be configured under the OSPF routing process on all routers
