A building permits desk sees OSPF neighbors stuck in 2-WAY on a shared Ethernet segment that already has a DR and BDR. Two additional routers remain DR-other. Is this necessarily a failure?
Select an answer to reveal the explanation.
Short Explanation
On multi-access Ethernet, only the DR and BDR need the full database dance with everyone. Two DR-others waving politely in 2-WAY at each other is normal—not a ticket. Panic if they can’t go FULL with the DR/BDR.
Full Explanation
On OSPF broadcast segments, DR-other routers form FULL adjacencies with the DR and BDR but typically remain 2-WAY with other DR-others. That behavior reduces adjacency count and is expected, not an inherent failure. Authentication failures or protocol replacement are separate issues and are not implied by DR-other 2-WAY state alone.
