You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor comman d output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem?（）
A. DR and BDR election errors between R1 and R2.
B. The R2 router has not received the OSPF hello packets from the R1 router.
C. Mismatched interface ma ximum transmission unit (MTU) configuration between the R1 and R2.
D. Mismatched OSPF hello interval configuration between the R1 and R2
E. Corrupted LSAs exchanges between the R1 and R2.

You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.What could be the cause of this problem?（）A. OSPF authentication errors between some of the routersB. Two routers have the same OSPF router IDC. Issues with mistuned OSPF timersD. OSPF LSA pacing issues between some of the routersE. OSPF neighbor adjacency problems between some of the routers

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.
