Bridge, bonding and vlan

[luigi]

Hello everyone.
I have a proxmox cluster with 3 node. In figure attached I show only two nodes.
On each server I have only 4 ethernet port, let me say eth1, eth2, eth3 and eth4.
I need of 4 VLAN:
VLAN10 (Production) - Must go on internet with default gateway 192.168.10.254
VLAN20 (Cluster) - proxmox cluster, internal network
VLAN30 (Management) - Must go on internet with default gateway 192.168.30.254
VLAN40 (Migration VM) - internal network

I thought of a solution like the one shown below.
I wold create two bridg:e
vmbr0 with default gw 192.168.10.254
vmbr1 with default gw 192.168.30.254

On vmbr0 I would create Bond0 interface with eth1,eth2 interfaces and vlan VLAN10, VLAN20 and on vmbr1 I would create Bond1 interface with eth3,eth4 interfaces and vlan VLAN30, VLAN40

I have two questions:
- Is it right the above solution?
- How to implement this solution on Proxmox?

Best regards, Luigi

2 default gateways are only useful if you define criteria which gateway have to be used in which case (and cannot be defined btw. in Proxmox WEB GUI), e.g. policy routing with different route tables, see https://blog.scottlowe.org/2013/05/29/a-quick-introduction-to-linux-policy-routing/

Note: this is possible in a Proxmox host since it's Linux Debian, but not a Proxmox supported feature so if you use it it's at your own risk.

I have two questions:

Depends on your need - a general answer is not possible. Just a remark regarding cluster network: we recommend to separate it physically, just a vlan separation is to less.

- How to implement this solution on Proxmox?

Regrding gateways as mentioned above, regarding vlans see chapter "VLAN on the Host" from https://pve.proxmox.com/wiki/Network_Configuration#_vlan_802_1q
