Refer to the exhibit. An administrator applies the configurations to routers R1 and R2 respectively. Both routers use the FastEthernet0/0 interface to connect to the same Ethernet switch. However, a neighbor adjacency fails to form. What is a possible cause for the problem?

  • The process IDs on R1 and R2 are identical.
  • The router IDs on R1 and R2 are mismatched.
  • The area numbers on R1 and R2 are mismatched.
  • The interval timers have not been set.

Explanation: Area membership is set at the interface level, and the area ID is included in the OSPF hello packet. An interface can belong to only one area. All routers within the same OSPF area maintain an identical copy of the LSDB.
