AAR

 Application aware routing is centralized Policy .

In Centralized Policy further classification it's data Plane Policy ( because it will impact site to site user traffic )

Conclusions : Centralized Data plane policy.

Site A ---- Site B have IPsec tunnel over MPls ( Private 1 ) and IPsec tunnel over Internet ( public ). By default communication from site A to site B for application will be done by both path ( equal cost multi path ) .

But I want to apply policy to utilise MPLS for critical services like video call , so I will preferred path color Private 1 for video call and backup path public

I will preferred path FTP or less equal priority traffic from A to B from ISP tunnel
