The Proxmox SDN feature does not play nice with our FRR and VXLAN setup.
With a single bridge we can’t have interface aliases. So use a bridge
for each VLAN. Actually don’t even have VLANs, just bridges mainlined
into VXLAN tunnels.
Read the list of VLANs carried by Proxmox nodes from a custom field on
the cluster in NetBox. Remove the vmbr0 device from individual nodes.
