Best place to configure VLANs: Core Switch vs Peplink 3?

Hi everyone,

I have a question regarding VLAN setup in a network.
In my infrastructure, I have a core switch and a Peplink 3 (router/firewall). Should the VLANs be created and configured on the core switch, or directly on the Peplink 3?

Which approach is considered best practice, and why?

Thanks in advance for your advice!
