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.
