@yogijain Hi,
Here are some examples,
Smart policy routing (SPR) allows devices to select routes based on link quality and requirements for link quality.
Intelligent Diagnosis, the system can find possible causes and provide suggestions, helping rapidly resolve network faults.
Intelligent Timer for Generating LSAs help to adjust the interval to generate the LSAs dynamiclly and automatically.
For me, the most open and free feature is OPS, it allows the administrator to customized the router as they wanted.
For all the features, you could find them in the product documentation.
Hope you like it.
