Question:

What is the purpose of using the multi-exit discriminator attribute on multiple BGP routers in an AS?

  • to help determine the best-path to a destination network
  • to advertise the peer group to another AS
  • to influence the inbound traffic flow from a different AS
  • to set the preference of an internal router to affect sending outbound traffic

Explanation: The BGP multi-exit discriminator (MED) attribute is nontransitive. The purpose of using MED is to influence traffic flows inbound from a different AS. A lower MED is preferred over a higher MED.
