OSPF Neighbors
Address of the neighbor.Address
Interface through which the neighbor is reachable.Interface
Generally, only the Down state, indicating a failed OSPF

neighbor is in only briefly while an OSPF adjacency is
being established.
State of the neighbor: Attempt, Down, Exchange, ExStart,
Full, Init, Loading, or 2way.
