MED Propagation in a BGP Network

The figure shows how the value of the MED attribute is assigned, depending upon the routing information source. A route-map must be configured on a router to manually assign a value to the MED attribute. For the networks that are also present in the BGP table, the router assigns a default value from the metric in the routing table and copies it into the MED attribute. The MED attribute is automatically removed on external sessions if the attribute did not originate in the local AS.
