   Refer to the exhibit. An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500. Traffic destined to AS 111 network 91.7.0.0/16 should come in via AS 100, while traffic destined to all other networks in AS 111 should continue to use the existing path. Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 into the 91.7.0.0/16 network?

   • AUse local preference on R1 for the networks that AS 500 advertises to AS 111
   • BPrepend AS path for the 91.7.0.0/16 network and set it for neighbor in AS 200
   • CUse extended community for the 91.7.0.0/16 network, not advertising it to the bi-lateral peer
   • DSet higher MED for neighbor in AS 100 to influence incoming traffic for the 91.7.0.0/16 network
