Correct Answer:
To ensure that traffic from R2 destined for 2001:db9:ffff:ff00::/62 always traverses the R2-R1 link if that link is available, the correct configuration is to export the specific route from Level 2 to Level 1 on R1. This will allow R2 (which operates as a Level 1 router) to receive the route and prioritize the R2-R1 link for traffic to the datacenter. Given the configurations provided, the correct answer is A. This configuration correctly exports the route from Level 2 to Level 1 on R1, thus fulfilling the requirement.

Aug 13, 2021Agree with Answer A. 1# the config has to be done on R1, as R1 is in Level 2 and has to export the route to layer 1. Answer B is the wrong router to do configuration on and C is routes from area 1 to area 2.
