Question 440
Two OSPF DROther routers on a normal broadcast Ethernet LAN show each other in 2-Way state, while both have Full adjacencies with the DR/BDR. Is this behavior necessarily a fault?
Explanation
Correct Answer
OSPF limits full adjacency requirements on a multiaccess broadcast network; not every DROther pair exchanges its complete database directly.
Incorrect Answers
Broadcast networks normally use DR/BDR to limit which neighbors fully synchronize.
Mismatched masks can be a problem, but the described normal DROther relationship alone does not establish it.
2-Way reflects bidirectional hello recognition, not an absence of hello reception.
