   You have two links to your ISP, one via a primary provider and one via a backup provider. You want to influence the ISP to send more inbound traffic through the primary link. You have already set a lower MED on the primary link. However, the ISP is still sending traffic through the backup link. What is the most likely reason?

   • AThe ISP has a higher local preference for the backup link.
   • BThe ISP is using AS-path prepending on the backup link, making it less preferred.
   • CThe MED value you set is not lower than the default.
   • DThe ISP is not comparing MEDs because the routes are from different ASes.
