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
OSPF states for adjacency formation are (in order) Down, Init, Attempt, 2-way, Exstart, Exchange, Loading and Full.
Why Are OSPF Neighbors Stuck in Exstart/Exchange State?
