Linux bridge + VLAN routing

[showiproute]

Hello there,
just a short question regarding VLAN routing.
I host several VMs with several VLAN subnets including a virtual router for intervlan routing on one Proxmox server.

If a VM from VLAN10 would send data over to a VM on VLAN20 would those connection leave Proxmox to get to a switch or would that be handled by the Linux bridge?

Both in case those bridges are also connected to a vlan capable switch. If that reduces performance depends on how that intervlan router VM is set up. Without PCI passthrough of the routers NICs you should get the good local bridge to bridge performance only limited by the performance of your CPU and router.

Yes, my bridge is VLAN aware and also connected to a VLAN capable switch.
