sandbox setup under PVE

[militarymedic23]

Wanted to ask a setup question for testing OPN virtually before going live.

Currently running Untangle/Arista on a Protecli type box, but aim to move over to OPN when my subscription ends.

I have a PVE server setup and have an OPN instance running.  slowly getting the hang of it.  But what I'd prefer to do for a learning scenario is try and create a virtual lab (mini mirror of end devices on different vlans) in PVE but behind OPN so I can iron out the networking changes then configure and tweak the various OPN components to what is needed.

One piece I'm trying to figure out is how to virtually emulate a L3 switch setup that is doing all my vlan routing on hardware.  Currently Arista just hands off traffic to the switch on vlan 1/switch IP and it routes it accordingly.

I understand this is overlapping a bit on the PVE side, but I'm hoping someone could offer some comments from either or both sides of the house.
