After injecting some traffic, we can check the Path Control, Links view to see that at least one LSP has been rerouted to bypass links where utilization exceeds the configured threshold value of 10%.

Note: To demonstrate this particular use case, the iPerf3 tool was used to inject traffic (i.e. to simulate real-live traffic). 

Example, before optimization:

Example, after optimization:

None of the links has available bandwidth lower than 9 000 Mbps. The network has optimized itself; redirecting LSPs to other links.

The change to the path is clear in the network map.
