Separated networks, two NIC, two vmbr

[Potkal]

Hi evryone this is my firrst time

My english is'n native so... mayby you uderstand me... or not

1. My node has 4xNIC 1GB and 2xNIC 10GB
2. I use 1x1GB for mgmt+data, 1x10GB for Backup, 1x10GB Ceph

Working network configuration:
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto eno1.272
iface eno1.272 inet static
address 10.1.2.114
netmask 24
gateway 10.1.2.1
vlan-raw-device eno1
#MGMT

iface eno2 inet manual
iface eno3 inet manual
iface eno4 inet manual

auto ens1f0
iface ens1f0 inet manual

auto ens1f0.291
iface ens1f0.291 inet static
address 172.16.11.114
netmask 24
#SAN

auto ens1f1
iface ens1f1 inet manual

auto ens1f1.281
iface ens1f1.281 inet static
address 172.16.1.114
netmask 24
#BACKUP

auto vmbr0
iface vmbr0 inet manual
bridge-ports eno1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

All interfacess are conected to switch as Trunk port.

My problem (question) is:

How to configure second vmbr to work with Backup network with VM and Node in the same time?

When I change:
auto ens1f1.281
iface ens1f1.281 inet static
address 172.16.1.114
netmask 24
vlan-raw-device ens1f1
#BACKUP

and i add:
auto vmbr281
iface vmbr281 inet manual
bridge-ports ens1f1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 281

The backup network is reachable from pve, not from VM.

When I use like that:
auto vmbr281
iface vmbr281 inet manual
bridge-ports ens1f1.281
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

Backup network works on VM but not on Node

on 1xGB (data+mgmt)works all ok
I was reboot, shutdown VM after adding vmbr0 - nothing change
I was try use Vid on VM - nothing change

Please help...

This is easy.

You make your new bridge (vmbr) and bridge it to the physical network interface you use for backups. Now you remove the IP configuration from the physical interface:

auto ens1f1.281
iface ens1f1.281 inet static
address 172.16.1.114
netmask 24
vlan-raw-device ens1f1
#BACKUP

And you set the proxmox IP on the new VMBR interface only, not the physical interface.

But i need connect to Node and VM
see on:
eno1 and vmbr0 - thats works
when i make that same on with
ens1f1 and vmbr281 - not work

(in VM with both vmbr's)
