Proxmox SDN: When VXLAN and EVPN Zones Actually Beat a VLAN-Aware Bridge
Proxmox has had a Software Defined Networking (SDN) subsystem built into the web UI for several versions now, living under Datacenter > SDN, and most homelabbers never open that tab. That’s reasonable: a VLAN-aware bridge and a managed switch trunk port solve network segmentation for a single-node or small-cluster homelab just fine, and that’s the setup covered in most Proxmox networking guides, including the basic bridges-and-VLANs approach. SDN solves a different, narrower problem, and it’s worth understanding what that problem is before reaching for it, because it adds real operational complexity that isn’t justified unless you actually have the problem it’s built for. ...
