Compare-Different-As-Med (Ipv6 Address Family View) - H3C S5820X Series Command Reference Manual

Description
Use the bestroute med-confederation command to enable the comparison of the MED for paths
from confederation peers for best route selection.
Use the undo bestroute med-confederation command to disable the configuration.
By default, this comparison is not enabled.
With this feature enabled, the system can only compare the MED for paths from peers within the
confederation. Paths from external ASs are advertised throughout the confederation without MED
comparison.
