Routing in Proxmox/Linux?
Hello everyone, help me understand how to do it right?
There is a node on Proxmox
There are two network interfaces eno1, eno2
They are combined in bond0
There are two vmbr10 and vmbr20
vmbr10- 10.10.0.1/24 (vlan10)
vmbr20- 10.20.0.1/24 (vlan20)
Default - vmbr10 it is with a gateway
Linux is also created vlan(10/20) that refer to bond0
I need all traffic for 10.20.0.0/24 to go through my vmbr20-10.20.0.1(vlan20) and not load the main (default) vmbr10
read that this is configured via iproute2 and so on did, but nifiga does not work
right, do I understand that traffic should be routed through the bridge (vmbr20) ?? or I'm wrong?

post-up ip route add default via 10.20.0.1 dev vmbr20 table rt2
post-up ip rule add from 10.20.0.1/24 table rt2

In view of the fact that IP 10.20.0.1 is added to the interface, subnet 10.20.0.0/24 is directly connected and traffic can freely go to it through vmbr20. No route rules are needed.
The goal that you are trying to achieve is not clear, and therefore I will explain: VLAN technology only allows you to divide the physical network into logical networks isolated from each other. VLANs will not help to increase the throughput in any way.
Thus, if traffic in one VLAN utilizes the interface bandwidth by 100%, and no limits or QoS are configured, then traffic in another VLAN will inevitably degrade - there is only one physical interface.
If you want to avoid this, remove BOND. Assign VLANs each to your interface. Or set up QoS.
I'm going to take a gtx 960, they promise to release it soon.
They just have consumption almost 2 times lower, and performance is higher. And the price should be up to 10k. Unless, of course, by then the dollar has not jumped much.
Read this article www.overclockers.ru/lab/62218/Vybor_optimalnoj_vid...
and choose the best option for yourself
For example this Asus GeForce GTX 760 OC 2048MB 256bit GDDR5 [GTX760-DC2OC-2GD5]. Worth just 10k.
