Configure VLAN-Aware Bridge and VLAN Subinterfaces on Proxmox¶
Builds the VLAN-aware bridge and per-VLAN gateway subinterfaces that underpin every workload environment in a HybridOps site. Covers vmbr0 configuration with bridge-vlan-aware yes, subinterface gateways for each VLAN in the standard allocation (VLANs 10–50), and routing validation from a test VM. This is the manual equivalent of what the core/onprem/network-sdn module manages in production.
What this covers:
- VLAN-aware bridge configuration on a live Proxmox VE host
- Per-VLAN gateway subinterfaces for management, observability, dev, staging, prod, and lab
- Safe apply-and-recover workflow with config backup and ifreload
