CLI Reference Guide
Use this command to include the Multi Exit Discriminator (MED) value between all
paths received from within the same autonomous system in the selection of the best
route selection. Use the no command to prevent BGP from considering the MED
attribute in comparing paths.
None.
Disabled
Router configuration
The bgp always-compare-med command is used to enable the comparison of the
Multi Exit Discriminator (MED) for paths from neighbors in different autonomous
systems. After the bgp always-compare-med command is configured, all paths for
the same prefix that are received from different neighbors, which are in the same
autonomous system, will be grouped together and sorted by the ascending MED
value (received-only paths are ignored and not grouped or sorted).
The best path selection algorithm will then pick the best paths using the existing rules;
the comparison is made on a peer neighbor autonomous system basis and then
global basis. The grouping and sorting of paths occurs immediately after this
command is entered. For correct results, all routers in the local autonomous system
must have this command enabled (or disabled).
The bgp deterministic-med command can be configured to enforce deterministic
comparison of the MED value between all paths received from within the same
autonomous system.
You can verify your settings by entering show ip bgp parameters command.
This example shows how to configure to enable compare MED value for autonomous
system 65534:
