  B. The age for newly created link state information is set to 1200 for OSPF and 0 for IS-IS
  C. The age is incremented or decremented as it is flooded from router to router and as it is held in the topological database.
  D. The age is incremented or decremented only as it is held in the topological database and not as it is flooded router to router.
  A. The age for newly created link state information is set to 0 for OSPF and 1200 for IS-IS
