Description
Use the compare-different-as-med command to enable the comparison of the MED
for paths from peers in different ASs.
Use the undo compare-different-as-med command to disable the comparison.
The comparison is disabled by default.
If there are several paths available for one destination, the path with the smallest MED
value is selected.
Do not use this command unless associated ASs adopt the same IGP protocol and
routing selection method.
