Field	Description
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.
