bgp always-compare-med

Description

Any changes in BGP configuration are applied by restarting the current BGP sessions in the VRFs.

The no form of this command disables comparison of MED.

Usage

• The MED is one of the parameters that is considered when selecting the best path among many alternative paths. The path with a lower MED is preferred over a path with a higher MED.

• During the best-path selection process, MED comparison is done only among paths from the same autonomous system. The bgp always-compare-med command is used to change this behavior by enforcing MED comparison between all paths, regardless of the autonomous system from which the paths are received.

Examples

Do you want to continue (y/n)?

switch(config-router)# no bgp always-compare-med
