Is OVS default in 5.4?

OVS is always optional.
 
Hi,

Thanks, I read from documentation that VLAN works out of the box in PVE, is it referring to Linux Bridging? Currently VLAN works within the same node but not across all nodes. Do you recommend to enable OVS in this case? What’s the easiest and simplest way to get VLAN work across all nodes?
