Mode6 aka loadbalance-alb

[0badc0de]

Hi all.
I would like to create a "mode 6" bond for both the main network interface (that for the VMs to gon online) and for the CEPH one in order to achieve both load balancing and fail over.
What I understand is that for the main network interface it couldn't work because of the network bridge that should be placed on top of the bond itself.
Is this true?

Hi,

What I understand is that for the main network interface it couldn't work because of the network bridge that should be placed on top of the bond itself.

Why should it not work when the vmbr is on top of this bond?

I've read about the fact that the handling/mangling of the MACs should happen to the bond level and that the (virtual) MACs would be seen only at the bridge level.
If this is not true, please confirm.

The mac address of the bridge has nothing to do with the bond mac address.
You have also a mac address at the nic and can use the bridge.

I think maybe I haven't been clear.
I need a loadbalance-alb (mode 6) bond in order to get load balancing also between just two machines.
With 802.3ad I won't get load balancing with just two machines. I will get it among a number of machines.
Now as far as I've understood, the mode 6 bond works at the bond level, while KVM needs a bridge on top of the bond.
That will work with 802.3ad. Will this setup actually work with a mode 6 bond?
I cannot do any test as I would disrupt some services and would like to know if anyone has enough details in advance.
