Enabling the enhanced ECMP mode
When one or multiple ECMP routes fail, the default ECMP mode enables the device to reallocate all

The enhanced ECMP mode enables the device to reallocate only the traffic of the failed routes to the
remaining routes, which ensures forwarding continuity.
This configuration takes effect at reboot. Make sure the reboot does not impact your network.
To enable the enhanced ECMP mode:
