33. What benefit is provided to OSPFv3 with the two new LSA types, type 8 and type 9?

  • They redistribute NSSA LSAs into an area.
  • They eliminate SPF calculations when interface addresses are added or changed.
  • They permit area routers to locate ASBRs in other areas.
  • They advertise default routes learned from other protocols into the OSPFv3 domain.

Explanation: Two new LSA types are added to OSPFv3, type 8, link-local LSA, and type 9, interarea prefix LSA. These two LSAs advertise unicast prefixes and prevent the need for OSPF calculations when interface addresses are added or changed.
