Comprehensive and Detailed Explanation:
OSPFv2 (for IPv4) and OSPFv3 (for IPv6) LSAs differ in function and naming conventions.
Key Differences in OSPFv3 LSAs:
* OSPFv3 does not use ASBR-Summary-LSA. Instead, it introduces new Inter-Area Prefix LSAs (Type 3) and Inter-Area Router LSAs (Type 4).
* OSPFv2 ASBR-Summary-LSA (Type 4) is replaced in OSPFv3 by Inter-Area Router LSA (Type
4).
OSPFv3 LSA Types:
# Router-LSA (Type 1) - Describes router interfaces and links.# Network-LSA (Type 2) - Describes broadcast network links.# Inter-Area Prefix LSA (Type 3) - Replaces Summary LSAs for routes.# Inter- Area Router LSA (Type 4) - Replaces ASBR Summary LSAs.# AS-External LSA (Type 5) - Describes external routes (same as OSPFv2).
Since ASBR-Summary-LSA (Type 4) does not exist in OSPFv3, the correct answer is A.
