Yes, it is a centrally managed SMB cluster. If I set non-monitored private, it will cause lost the ability of the virtual IP which is really important in that two trunc interface.
I know the cluster prerequisites, which describes between cluster interfaces must be layer 2 connection....
In a nutshell:
There is a special device with two interfaces:

On the special device (appliance) eth1 and eth2 is a linux bond trunc interface. This device is probing its default gateway on both interfaces. The traffic will flow on that IF, which receives the ARP answer faster.
And no, I can't put an active device there (router, switch, etc.) It is prohibited.
This is a very special scenario
Any idea will appreciate
