Question 200
An enterprise network designer recommends: Advertise an appropriate MED value on the relevant route toward that neighboring AS. Which situation most clearly calls for this action?
Explanation
Correct Answer
This case requires the BGP MED export action. The neighboring AS can use the metric when comparing eligible routes according to its policy.
Incorrect Answers
This other case would be better matched to Use a properly designed BGP route-reflector topology with client sessions. Reflector clients can receive eligible iBGP routes without a full direct mesh among all clients.
This other case would be better matched to Use a supported next-hop-self behavior at the iBGP advertisement point. Clients can resolve the advertised next hop through the advertising router when designed properly.
This other case would be better matched to Apply the well-known NO_EXPORT community to the selected advertisement. BGP speakers honoring the community avoid advertising the route to external AS peers.
