Refer to the exhibit. An engineer must ensure that all traffic entering AS 200 from AS 100 chooses Link 2 as an entry point. Assume that all BGP neighbor relationships have been formed and that the attributes have not been changed on any of the routers. Which configuration accomplishes this task?

  • A. R3(config)#route-map PREPEND permit 10
    R3(config-route-map)#set as-path prepend 200 200 200
    R3(config)#router bgp 200
    R3#(config-router)#neighbor 10.1.1.1 route-map PREPEND out
  • B. R4(config)#route-map PREPEND permit 10
    R4(config-route-map)#set as-path prepend 100 100 100
    R4(config)#router bgp 200
    R4(config-router)#neighbor 10.2.2.2 route-map PREPEND in
  • C. R4(config)#route-map PREPEND permit 10
    R4(config-route-map)#set as-path prepend 200 200 200
    R4(config)#router bgp 200
    R4(config-router)#neighbor 10.2.2.2 route-map PREPEND out
  • D. R3(config)#route-map PREPEND permit 10
    R3(config-route-map)#set as-path prepend 100 100 100
    R3(config)#router bgp 200
    R3(config-router)#neighbor 10.1.1.1 route-map PREPEND in
