View
IPv6 MBGP address family view
Default Level

Parameters

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.
By default, MED comparison is not allowed among the routes from the peers in different ASs.
If there are several paths for one destination available, the path with the smallest MED is selected.
Do not use this command unless associated ASs adopt the same IGP and routing selection method.
