Which OSPFv3 LSA type is generated by an ABR to advertise prefixes from one area to another?
In OSPFv3, an ABR (Area Border Router) generates Inter-Area Prefix LSAs to advertise prefixes from one area to another. This type of LSA allows the ABR to specify IPv6 prefixes that belong to other areas, ensuring proper routing information is shared between areas.
I think this is not correct. OSPFv3 LSA types state that AS Externals are originated by ASBRs, describing the destinations external to the AS. Since it's in the same routing domain, than, the correct answer appears to be the Inter-Area Prefix LSA, where it is stated that these LSA Types are originated by the ABR to specify IPv6 prefixes that belong to other areas. So IMO, D appears to be the correct answer.
correct Ans: D Inter-Area Prefix LSA: These LSAs are IPv6 equivalent of IPv4's Type-3 Summary LSAs. These LSAs are originated by the ABR to specify IPv6 prefixes that belong to other areas. A separate LSA is originated for each address prefix. For Stub areas, the Inter-area Prefix LSA is used to describe a default route. The prefix length of the default route is set to 0.
D is correct
Error there, correct answer is D. A would be the answer to question “Which OSPFv3 LSA type is generated by an ASBR to advertise prefixes from one domain to another?”
