   Your AS 65001 has two eBGP connections to AS 65002. You want AS 65002 to prefer the Dallas link for inbound traffic. You have configured MED on the Dallas link to be 50 and on the Houston link to be 100. However, you notice that AS 65002 is still using the Houston link for some prefixes. What is a likely reason for this behavior?

   • AAS 65002 is using AS path prepending to prefer the Houston link.
   • BAS 65002 is not receiving the MED attribute because it is optional non-transitive.
   • CAS 65002 is comparing MED across different ASes, which is not allowed by default.
   • DAS 65002 has a higher local preference for the Houston link.
