WebBGP MED The MED is an optional attribute that comes in handy when there are multiple entrance paths to an AS. The remote AS sets MED values to tell the other AS which path to use. The MED is passed between the two autonomous systems, but the value is not passed to any other ASes. The path with the lowest MED is the preferred path.
