Description
■ Use the compare-different-as-med command to enable comparison of MED
values from different AS neighboring routes when determining the best route.
■ Use the undo compare-different-as-med command to disable the
comparison.
By default, it is disabled to compare the MED attribute values from the routing
paths of different AS peers.
If there are several routes available to one destination address, the route with
smaller MED parameter can be selected as the final route item.
Do not use this command unless it is determined that the same IGP and routing
selection mode are adopted by different autonomous systems.
