Comprehensive and Detailed In-Depth Explanation:

InOSPFv3, theAS-external-LSA (Type 5 LSA)is the only LSA type that can beflooded throughout the entire Autonomous System (AS). It is used to advertise external routes (routes redistributed from other routing protocols or static routes) into the OSPF domain.

B. Intra-Area-Prefix-LSA (Type 9):Used to advertise IPv6 prefixes within an OSPF area, not across the AS.

C. Link-LSA (Type 8):Advertises link-local addresses and options, only within the local link, not the entire AS.

D. Inter-Area-Prefix-LSA (Type 3 or Type 4):Advertises prefixes between OSPF areas but not throughout the entire AS.

OnlyAS-external-LSAs (Type 5)can be propagated across the whole OSPF AS, making them essential for exchanging routes learned from other routing protocols.
