Comprehensive and Detailed In-Depth Explanation:
To determine which statements are false, we need to understand how OSPFv3 and IS-IS work together, and how Inter-Area-Router LSAs (Type 3 LSAs) are generated in OSPF:
1. Understanding OSPF Inter-Area LSAs (Type 3)
* OSPF generates Type 3 LSAs (Inter-Area-Prefix LSAs) to advertise networks between areas.
* Only Area Border Routers (ABRs) generate Inter-Area LSAs.
* Type 3 LSAs allow routes to be advertised from one OSPF area to another (e.g., from Area 0 to Area 1 or Area 2).
2. Analysis of Each Answer Option:
# A. "R3 generates an Inter-Area-Router-LSA in Area 0." # TRUE
* R3 is an ABR (connecting IS-IS and OSPF Area 0).
* Since R3 is importing IS-IS routes into OSPFv3, it must generate Type 3 LSAs to advertise those routes in Area 0.
* This statement is correct.
# B. "R2 generates an Inter-Area-Router-LSA in Area 0." # TRUE
* R2 is also an ABR (connecting IS-IS and OSPF Area 0).
* Like R3, R2 imports IS-IS routes into OSPFv3 and advertises them into Area 0 using Type 3 LSAs.
* This statement is correct.
# C. "R1 generates an Inter-Area-Router-LSA in Area 2." # FALSE
* R1 is not an ABR.
* Only ABRs generate Type 3 LSAs, and R1 is not an ABR between Area 2 and Area 0.
* This statement is false.
# D. "R2 generates an Inter-Area-Router-LSA in Area 1." # FALSE
* Area 1 is a stub area, and stub areas do not allow Inter-Area-Router LSAs (Type 3 LSAs) for external routes.
* R2 does not generate Inter-Area LSAs in Area 1 because OSPF prevents this in stub areas.
* This statement is false.
