Cisco CCNA 200-301 Practice Question

In OSPF (Open Shortest Path First), if a neighbor remains in the 'INIT' state, it means that a router is receiving hello packets from its neighbor but its own hello packets are not being acknowledged. The most common reason for this is mismatched hello and dead timers between the routers. OSPF requires these timers to be identical on both ends to form a full adjacency. Authentication mismatches or different network types typically prevent any adjacency from forming, not just keep it in the 'INIT' state. Using different process IDs does not affect neighbor relationships as long as the routers are in the same area and have matching network statements.
