Comprehensive and Detailed In-Depth Explanation:

Understanding the LSA Table in the Figure

The LSA Type displayed in the LSDB of R3 is an Intra-Area-Prefix-LSA (Type 9), with the following attributes:

LS Type: Intra-Area-Prefix-LSA (Type 9)

Link State ID: 0.0.0.1

Originating Router: 10.0.2.2 (R2)

Referenced LSA Type: 0x2001 (Router-LSA, Type 1)

Referenced Link State ID: 0.0.0.0

Referenced Originating Router: 10.0.2.2 (R2)

Prefix: 2000:2::/128

Analysis of the Statement

What is an Intra-Area-Prefix-LSA (Type 9)?

Used in OSPFv3 to advertise IPv6 prefixes associated with a Router-LSA (Type 1) or Network-LSA (Type 2).

Each router generates its own Router-LSA (Type 1) and references it in an Intra-Area-Prefix-LSA (Type 9).

How does this apply to R3's LSDB?

The LSA is generated by R2 (10.0.2.2), meaning R2 originated the prefix advertisement.

The referenced LSA is a Router-LSA, indicating that the IPv6 prefix is associated with R2's router advertisement.

Since R3 sees this LSA in its LSDB, it means R2 has advertised its IPv6 prefix (2000:2::/128) into the OSPFv3 domain.

✅ Since the LSA describes an IPv6 prefix associated with R2’s Router-LSA, the statement is TRUE.

Final Conclusion:

✅ The LSA is generated by R2 and describes the IPv6 prefix associated with the Router-LSA.✅ Thus, the correct answer is: A. TRUE.
