State/Dr
(cont.)
Exchange - In this state, the CSS sends DD packets to the
neighbor to describe its entire link-state database. Each DD
packet has a DD sequence number and is explicitly
acknowledged. Only one DD packet is allowed to be
outstanding at any one time. In this state, the CSS may also
send Link State Request packets, requesting the neighbor’s
more recent LSAs. All adjacencies in Exchange state (or
greater) are used by the flooding procedure. In fact, these
adjacencies are fully capable of transmitting and receiving all
types of OSPF routing protocol packets.
Loading - In this state, the CSS sends Link State Request
packets to the neighbor, requesting the more recent LSAs that
have been discovered (but not yet received) in the Exchange
state.
Full - In this state, the neighboring routers are fully adjacent.
These adjacencies will now appear in router LSAs and
network LSAs.
Type Always dynamic.
Rxmt_Q The number of LSAs to retransmit to the neighbors.
