Which of the following OSPF messages contains entire complete LSAs used during the
database exchange process?
A.
LSR
B.
LSAck
C.
LSU
D.
DD
E.
Hello
Explanation:
The Database Description (DD) packet lists a short LSA header but not the entire LSA. The
Link State Request (LSR) packet asks the neighbors for a copy of an LSA. The Link State
Update (LSU) holds the LSAs. LSAck simply acknowledges received LSAs, and Hello is
used for neighbor discovery and neighbor state maintenance.
