When a router undergoes the exchange protocol within OSPF, in what order does it pass through
each state?
A.
exstart state > loading state > exchange state > full state
B.
exstart state > exchange state > loading state > full state
C.
exstart state > full state > loading state > exchange state
D.
loading state > exchange state > full state > exstart state
During its course, each router conversation transitions through a maximum of eight conditions defined by a state machine.
ExStart: The ExStart state is the first step of adjacency of two routers.
Exchange: In the Exchange state, a router is sending its link state database information to the adjacent neighbor. At this state, a router is capable to exchange all OSPF routing protocol packets.
Loading: In the Loading state, a router requests the most recent Link-state advertisements (LSAs) from its neighbor discovered in the previous state.
Full: The Full state concludes the conversation when the routers are fully adjacent, and the state appears in all router- and network-LSAs. The link state databases of the neighbors are fully synchronized.
