The correct answer is B. Implement BGP weight capabilities on R1. BGP weight is a local attribute used by Cisco routers to influence the best path selection process. It is applied locally on a router and does not propagate to other routers. By assigning a higher weight to the path via R2 (next-hop 10.114.21.1), R1 can be configured to prefer th
Question
Refer to the exhibit, R1 is connected to multiple BGP-enabled routers that are located in different autonomous systems. R1 has been configured with a BGP neighbor configuration, and all next hops are reachable with the ICMP protocol. A network engineer is examining traffic flow to the FTP server with IP address 134.44.14.10 to support a policy map implementation. The solution should require the minimum possible configuration changes. What should the engineer do to influence the best path route selection algorithm to forward all traffic from R1 via next-hop R2 with IP address 10.114.21.1?

Explanation
BGP weight is a local attribute used by Cisco routers to influence the best path selection process. It is applied locally on a router and does not propagate to other routers. By assigning a higher weight to the path via R2 (next-hop 10.114.21.1), R1 can be configured to prefer this path for forwarding traffic to the FTP server at 134.44.14.10. This approach requires minimal changes since the weight attribute is only configured locally on R1 and does not affect the BGP configuration or routing behavior of other routers in the network.
