An OSPF database contains two router LSAs with identical link information indicating that one LSA is not valid.Which action will immediately clear the invalid LSA from the network without waiting for the LSA to time out or resetting the OSPF sessions on the router?
A.
user@router# deactivate protocols ospf
user@router# commit user
@router# activate protocols ospf
user@router# commit
B.
user@router> clear ospf database purge
C.
user@router> clear ospf database
D.
user@router> restart routing
I have tested on my lab, and C is more precise.

B Blows away the database for every router in the area. The question did ask to clear the invalid LSA from the network.

La respuesta debe ser b. debido a que al usar este comando reinicia el agetime a 0 y eso hace que el LSA invalido se quite de la db, por lo tanto es la respuesta mas optima.
en el caso de clear ospf database este comando borra toda la DB ospf y hace que los ruteadores vuelvan a intercambiar los paquetes DD y volver a llenar sus DB.

it should be B because it said “immediately clear the invalid LSA from the – network – ” not from the Router
