The Eatery, an international food services conglomerate, wants to implement wide area network links between its 25 plants spread across 13 countries. You have been brought in as a consultant on the project.

Hogan's suggests using a distance-vector routing protocol because of its relative simplicity. 

 Create a network design using the distance-vector protocol you feel will meet The Eatery's needs. What metrics are used by default? Which metrics can and should be configured? Justify your answer
