Configure VLAN-Aware Bridge and VLAN Subinterfaces on Proxmox¶
Builds the VLAN-aware bridge and per-VLAN gateway subinterfaces used by the shipped on-prem reference topology. Covers vmbr0 configuration with bridge-vlan-aware yes, subinterface gateways for the reference allocation (VLANs 10–50), and routing validation from a test VM. The same topology is delivered through core/onprem/network-sdn in the governed module path.
What this covers:
- VLAN-aware bridge configuration on a live Proxmox VE host
- Per-VLAN gateway subinterfaces for management, observability, dev, staging, prod, and validation
- Safe apply-and-recover workflow with config backup and ifreload
