No routers are adjacent with each other.B. Only Router A and Router B are adjacent at Level 1.C. Only Router A and Router B are adjacent at Level 2.D. All three routers are adjacent with each other at Level 1.

It is used with the OSPF priority values to determine which interface will be used to form a neighbor relationship with another OSPF routerC. It is used with the OSPF priority values to determine which router will become the DR or BOR in a multi access networkD. It is used to determine which interfaces will send Hello packets to neighboring OSPF routers

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.
