When SD-WAN is turned on, ECMP load-balancing mode will be disabled, and 'set v4-ecmp-mode source-ip-based' default CLI command from global settings will be removed.
 
 
To turn on ECMP load-balancing mode back, disable SD-WAN status.
 

 

Version 6.4 and above : 

 

The command 'config system virtual-wan-link' is removed starting from version 6.4.x. 

To disable or enable SDWAN status, apply the command below :  

 

 config system sdwan 

    set status disable 

 

After applying the change ECMP load-balancing will be turned on again.

 

show full-configuration | grep ecmp
    set v4-ecmp-mode source-ip-based  <-- ECMP enabled.
    set ecmp-max-paths 255
