Master Engine license limits
Master Engines use the same Secure SD-WAN Engine licenses as other Secure SD-WAN Engines. The Secure SD-WAN Engine licenses enable the Virtual Engine features.
Virtual Engines do not require their own licenses. However, the Secure SD-WAN Engine license limits the number of Virtual Resources that can be created. The limit for the number of Virtual Resources limits how many Virtual Engines can be created. You can optionally increase the allowed number of Virtual Resources by purchasing and installing a feature-specific license.
