- D. The Inter-Area-Prefix-LSA that is generated by R3 and describes 2000::6/128 exists in Area 2.
Answer: B,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
To determine the correct answers, we need to analyze OSPFv3 behavior and Inter-Area-Prefix LSAs (Type
3 LSAs).
1. Understanding OSPFv3 Inter-Area-Prefix LSAs (Type 3 LSAs)
* Type 3 LSAs (Inter-Area-Prefix LSAs) are generated by an ABR (Area Border Router) to advertise networks between areas.
* If a router in one area learns a prefix from another area, it generates a Type 3 LSA to advertise it further.
* Stub areas (Area 1) do not allow external LSAs, including Type 3 LSAs for external routes.
* NSSA areas (Area 3) accept external routes but redistribute them as Type 7 LSAs before being converted to Type 5 LSAs by an NSSA ABR.
2. Analyzing Each Answer Option:
# A. "The Inter-Area-Prefix-LSA that is generated by R1 and describes 2000::6/128 exists in Area 0." # TRUE
* R6 has 2000::6/128 in Area 2.
* R2 is the ABR that brings this prefix into Area 0 as a Type 3 LSA.
* R1, being in Area 0, learns this LSA from R2.
* Thus, this statement is correct.
# B. "The Inter-Area-Prefix-LSA that is generated by R1 and describes 2000::6/128 exists in Area 3." # FALSE
* R1 is not an ABR for Area 3, so it does not generate an LSA for 2000::6/128 in Area 3.
* Instead, R3 (the ABR between Area 0 and Area 3) would be responsible for propagating routes.
* This statement is false.
# C. "The Inter-Area-Prefix-LSA that is generated by R2 and describes 2000::6/128 exists in Area 1." # FALSE
* Area 1 is a stub area and does not accept external LSAs (including Type 3 LSAs from other areas).
* R2 cannot generate and send a Type 3 LSA for 2000::6/128 into Area 1.
* This statement is false.
# D. "The Inter-Area-Prefix-LSA that is generated by R3 and describes 2000::6/128 exists in Area 2." # TRUE
* R3 is an ABR and learns 2000::6/128 from R2 (which originally learned it from R6 in Area 2).
* Since Area 2 is a normal (non-stub, non-NSSA) area, Type 3 LSAs are allowed.
* R3 generates and advertises this Inter-Area-Prefix-LSA for 2000::6/128 into Area 2.
* Thus, this statement is correct.

In the network shown in the figure, R1, R2, R4, and R5 run IS-IS in area 49.0001, and R3 and R6 run IS-IS in area 49.0002. Within AS 65000, R1, R3, R4, and R6 establish IBGP neighbor relationships with R2 and R5, of which R2 and R5 are RRs and R1, R4, R3, and R6 are clients.
