Question:

What is a purpose of the OSPFv3 type 8 and type 9 LSAs?

  • advertise default and external routes learned from other protocols
  • eliminate the need for SPF calculations when interface addresses are added or changed
  • allow area routers to locate ASBRs in other areas
  • advertise NSSA LSAs for redistributed routes in an area

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.
