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.
