Down- initial state of the neighbor conversation - no recent information has been received from the
neighbor.
Attempt - no recent information has been received from the neighbor but a more concerted effort should be
made to contact the neighbor.
Init - an Hello packet has recently been seen from the neighbor, but bi-directional
communication has not yet been established.
2 way - communication between the two routers is bi-directional.
Exchange start - the first step in creating an adjacency between the two neighboring routers, the goal is to
decide which router is the master and to decide upon the initial DD sequence number.
Exchange - the router is describing its entire link state database by sending Database Description packets
to the neighbor.
Loading - Link State Request packets are sent to the neighbor asking for the more recent LSAs that have
been discovered (but not yet received) in the Exchange state.
Full - the neighboring routers are fully adjacent and they will now appear in router-LSAs and network-LSAs.
