Which of the following OSPFv3 LSA types is an intraareaprefix LSA? (Select the best answer.)

  • Type 3
  • Type 4
  • Type 5
  • Type 8
  • Type 9
Explanation:
Open Shortest Path First version 3 (OSPFv3) Type 9 linkstate advertisements (LSAs) are intraareaprefix LSAs. OSPFv3 Type 9 LSAs carry IPv6 prefix information, much like OSPF version 2 (OSPFv2) Type 1 and Type 2 LSAs carry IPv4 prefix information. In OSPFv3, Type 1 and Type 2 LSAs no longer carry route prefixes. LSAs carry only routing information; they do not contain a full network topology. Both Type 9 LSAs and Type 8 LSAs are new in OSPFv3.
OSPFv3 Type 8 LSAs are link LSAs. Type 8 LSAs are used to advertise the router’s linklocal IPv6 address, prefix, and option information. These LSAs are never flooded outside the local link.
OSPFv3 Type 3 LSAs are interareaprefix LSAs for area border routers (ABRs). Type 3 LSAs are used to advertise internal networks to other areas. Like Type 9 LSAs, Type 3 LSAs also carry IPv6 prefix information.
OSPFv3 Type 4 LSAs are interarearouter LSAs for autonomous system boundary routers (ASBRs). Type 4 LSAs are used to advertise the location of an ASBR so that routers can determine the best nexthop path to an external network.
OSPFv3 Type 5 LSAs are autonomous system (AS)external LSAs. Type 5 LSAs are used to advertise external routes that are redistributed into OSPF.
