ip bgp always-compare-med
Enables or disables Multi-Exit Discriminator (MED) comparison between peers in different autonomous
systems. The MED value is considered when selecting the best path among alternatives; it indicates the
weight for a particular exit point from the AS. A path with a lower MED value is preferred over a path
with a higher MED value.

Usage Guidelines
•
Use the no form of this command to disable MED comparison for external peers.
•
By default, BGP only compares MEDs from the same autonomous system when selecting routes.
Enabling this command forces BGP to also compare MEDs values received from external peers, or
other autonomous systems.
•
The BGP protocol must be disabled (using the ip bgp admin-state command) before using this
command.
