Description Use the bestroute med-confederationcommand 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 comparison.

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.

Examples # Compare the MED for paths from peers within the confederation.

<Sysname> system-view [Sysname] bgp 100 [Sysname-bgp] ipv6-family

[Sysname-bgp-af-ipv6] bestroute med-confederation

Use the undo compare-different-as-medcommand 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.
