Exam 350-501 topic 1 question 20 discussion

100% Correct Answer is A Concept in Route target is very simple "export in VRF1 equal import in VRF2" and visa versa - IMPORT-RT in ABC must not equal EXPORT RT in XYZ and visa versa - IMPORT RT in (ABC,XYZ) must equal EXPORT RT in CENTRAL and visa versa IMPORT-RT in Central equal EXPORT-RT in (ABC,XYZ)

100% Correct Answer is A

Among the given options, A is the most correct one

100% Correct Answer is A Router with VRF ABC --- Route Distinguisher: 65000:1 (default for vrf ABC) *> 2.2.2.2/32 0.0.0.0 0 32768 ? ip vrf ABC rd 65000:1 route-target export 65000:1111 route-target export 65000:3333 route-target import 65000:1111 route-target import 65000:4444 Router with VRF XYZ ---- Route Distinguisher: 65000:2 (default for vrf XYZ) *> 3.3.3.3/32 0.0.0.0 0 32768 ? ip vrf XYZ rd 65000:2 route-target export 65000:2222 route-target export 65000:3333 route-target import 65000:2222 route-target import 65000:4444 Router with VRF CENTRAL --- Route Distinguisher: 65000:3 (default for vrf CENTRAL) *>i 2.2.2.2/32 10.50.50.50 0 100 0 ? *>i 3.3.3.3/32 10.50.50.50 0 100 0 ? ip vrf CENTRAL rd 65000:3 route-target export 65000:4444 route-target import 65000:3333

Before you comment.... everyone here knows "A" is the correct answer....

A is correct

I still think its B heres why: Central VRF keeps it seperated by not communicating back to the same imports of ABC and XYZ. Using that knowledge Answer A and Answer D is eliminated. C just doesnt make sense.

Should be A

Correct answer is A

I Agree, the anwer is "A"!

I disagree to all of you, correct answer is A

Agree that answer is A, that is the only configuration that achieves the desired effect. Option B, VRF XYX Exports both 65000:1111 and 65000:2222, which means that VRF ABC imports RT 65000:1111, then it would receive VRF XYZ routes as well.
