On the network shown in the figure, IS-IS IPv6 runs on R2, R6, and R3,...

[Reference: HCIP-Datacom-Advanced Routing & Switching Technology, IS-IS IPv6 Routing Principles., B. "The routing table of R5 contains the route 2000::6/128." → TRUE, R6 advertises 2000::6/128 via IS-IS to R3 and R2., R3 imports the IS-IS routes into OSPFv3 Area 0., Since R5 is in Area 2 (NSSA) and Area 2 can accept external routes (as NSSA external LSAs), R5 will learn 2000::6/128 from R3., Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF NSSA Route Handling., C. "The routing table of R4 contains the route 2000::6/128." → TRUE, R4 is in Area 1 (Stub Area)., While Area 1 does not accept external routes, R4 still learns inter-area routes from Area 0 via R3., Since R3 redistributes 2000::6/128 into OSPFv3 Area 0, and R4 learns it from R3, R4 will have 2000::6/128 in its routing table., Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF Inter-Area Route Handling., D. "The routing table of R1 contains the route 2000::6/128." → TRUE, R1 is connected to R3, which is in Area 0., Since R3 has imported IS-IS routes into OSPFv3, R1 will learn 2000::6/128 through OSPF Area 0 as an inter-area route., Reference: HCIP-Datacom-Advanced Routing & Switching Technology, OSPF Route Redistribution and Inter-Area Routing., , , , ]
