Which configuration will resolve connectivity for both sites of customer_a?

A. ip vrf customer_a

rd 1:2

route-target both 1:1

B. ip vrf customer_a

rd 1:2

route-target both 1:2

C. ip vrf customer_a

rd 1:1

router-target import 1:1

router-target export 1:2

D. ip vrf customer_a

rd 1:1

route-target export 1:2

router-target import 1:2

Answer: A

Explanation:

From the exhibit, we learned:

+ VRF customer_a was exported with Route target (RT) of 1:1 so at the remote site it must be imported with the same RT 1:1.

+ VRF customer_a was imported with Route target (RT) of 1:1 so at the remote site it must be exported with the same RT 1:1.

Therefore at the remote site we must configure the command “route-target both 1:1” (which is equivalent to two commands “route-target import 1:1” & “route-target export 1:1”.
