Compare-Different-As-Med (Mbgp Family View) - 3Com S7906E Command Reference Manual

Description
Use the bestroute med-confederation command to enable the comparison of the MED for paths from
confederation peers during best route selection.
Use the undo bestroute med-confederation command to disable the comparison.
The comparison is not enabled by default.
The system only compares MED values for paths from peers within the confederation. Paths from
external ASs are advertised throughout the confederation without MED comparison.
