Selected Answer: D
VPN-A sends point-to-point traffic to VPN-B -> VPN-B must import RT value that VPN-A exports (100:1).

Considering MP-BGP + MPLS which are not in the scope of ENCOR the D is the correct. So I realy wonder why is this question in place since it is completely outside of scope.

Good point - cannot export what you don't originate so this rules out A & C. Of B & D only D matches the flow described.

Analyzing this question with the comments you all gave clarified a lot with this RD/RT business. OCG did a horrible job explaining communities in relation to VRFs.

4 retarded amigos who wrote OCG dedicated TWO PAGES for VRF (VRF-lite to be exact). so yeah, VRF was covered in maybe 5%.

PE-3 vrf VPN-B address-family ipv4 unicast import route-target 100:2 export route-target 100:2 C. PE-2 vrf VPN-B address-family ipv4 unicast import route-target 100:2 export route-target 100:2 D.

Niyi, you cannot export what you don't originate. Your export route-target 100:2 from PE-3 is not appropriate. That is why the post answer "A" is right.

Can anyone tell me why the suggested answer is A? From my acknowledgement, the answer is D. I do not understand why the answer is A.

So I just worked it out to be A myself. I have little to no knowledge of this topic so I was using logical deduction. I thought that the question was asking what configuration is causing VPN C to response to VPN A when VPN A wants to talk to VPN B. Answer option A was the only one that I could think that could be causing that. Now that I have seen that everyone is saying it's D. I'm just confused.

Just realised that my initial reasoning makes no sense... I'm not sure how I arrived at that conclusion. Answer option D is the only one that would make sense. I must have misread the question.

Answer is D Export of 100:2 makes sense only from PE3, which excludes answers A and C. VPN-C receives traffic from VPN-A, so PE-3 imported 100:1. That is answer D

I also realized for answer B, it would be importing its own routes (PE-3 import 100.2 which is its own RD) and that doesn't make sense either. So only answer that makes any sense would be D.
