OSPF neighbor never goes to Full state


An Open Shortest Path First (OSPF) neighbor status that does not reach the Full state does not necessarily represent a problem.

OSPF neighbors can be in any one of the following states:

  • Down
  • Attempt
  • Init
  • 2-Way
  • Exstart
  • Exchange
  • Loading
  • Full

For more information on OSPF neighbor states, refer to OSPF Neighbor Problems Explained.
