質問 # 39
Refer to the exhibit. The service provider operations team was alerted that hub site traffic from BGP AS 65101 to AS 65201 uses a non-primary path via the R5-R6 link.

Which action resolves this issue?

A. Change the local-preference attribute to 50 with neighbor 10.10.10.5 on R1.
B. Set the local-preference to the default value with BGP neighbor 10.10.10.3 on R2 for receiving routes.
