Field State Mode Priority DR BDR MTU Options Dead timer due in 33 sec Neighbor is up for 02:03:35 Authentication Sequence Neighbor state change count Description Neighbor state: • Down-Initial state of a neighbor conversation. • Init-The router has seen a Hello packet from the neighbor. However, the router has not established bidirectional communication with the neighbor (the router itself did not appear in the neighbor's hello packet). • Attempt- Available only in an NBMA network, Under this state, the OSPF router has not received any information from a neighbor for a period but can send Hello packets at a longer interval to keep neighbor relationship. • 2-Way-Communication between the two routers is bidirectional. The router itself appears in the neighbor's Hello packet. • Exstart-The goal of this state is to decide which router is the master, and to decide upon the initial Database Description (DD) sequence number. • Exchange-The router is sending DD packets to the neighbor, describing its entire link-state database. • Loading-The router sends LSRs packets to the neighbor, requesting more recent LSAs. • Full-The neighboring routers are fully adjacent. Neighbor mode for LSDB synchronization. Neighboring router priority. DR on the interface's network segment. BDR on the interface's network segment. Interface MTU. LSA options: • O-Opaque LSA advertisement capability. • E-AS External LSA reception capability. • EA-External extended LSA reception capability. • DC-On-demand link support. • N-NSSA external LSA support. • P-Capability of an NSSA ABR to translate Type-7 LSAs into Type-5 LSAs.
