When learning a new route, if a LSA received is not found in the topological database, what
will an internal OSPF router do?

A.
The sequence numbers are checked, and if the LSA is valid it is entered into the topology
database.

B.
The LSA is placed in the topological database and an acknowledgement is sent to the
transmitting router.

C.
The LSA is dropped and a message is sent to the transmitting router.

D.
The LSA is flooded immediately out of all the OSPF interfaces, except the interface from
which the LSA was received.
