Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 369

In which state do DR and BDR establish adjacency with each OSPF router in the network?

Answer options

• A. Init State
• B. Exstart State
• C. Exchange State
• D. Loading State

Correct answer: A

Explanation

The correct answer is A, Init State, as this is the phase where OSPF routers first attempt to establish adjacency. In this state, routers send Hello packets to discover other OSPF routers. The other states, Exstart, Exchange, and Loading, occur later in the process when routers have already established initial communication.
