Connect two nodes for clustering via LAN directly

[marivesel]

I have the following:

Node-1 with 3 NICs - one for Proxmox UI, one for Internet, and last for direct connection to Node-2
Node-2 with 3 NICs --||--||--||-- the same

They can see each other via the "Internet" NICs (which are connected to the same switch)
But I can't manage the the two nodes to ping each other via the directly connected NICs with LAN cable

I have configured Linux Bridge for the "direct connection" NIC with 10.15.15.1/32
The same on the other node - Linux Bridge for the "direct connection" NIC with 10.15.15.2/32

The hardware NICs seems connected (there is flashing light on the RJ45 ports), but I can't ping from Node-1 to Node-2 and vice-versa.

I want to make the "direct connection" LAN to be my network for Clustering only.
How to do it?

Regards.

You’re sure /32 is right? Shouldn’t that be /8?

you should use a /30 at minimum, to have 2 usable ip address + broadcast + network address.

(or /31 with specific static routes)
