Host with two network connections (STP needed?)

I have two hosts (pve0 & pve1). The hosts both have two nics bonded to my switch with an ip on the range 192.168.86.0/24. I have also connected the nucs together via a thunderbolt cable.

Ideally I'd like as much traffic to go via the thunderbolt cable as its very quick compared to the ethernet connection, but I'd like to always be able to fail back to ethernet, and all external traffic (and the wider network) must go via ethernet.

I've configured my bridge up as follows on pve0:

and like this on pve1:

Running iper3 on pve0 to pve1 shows this:

pve1 runs a host on ip 192.168.86.61. Running iperf3 from pve0 to the host on pve1 shows this:

so I think the network is really unhappy with the loop.

Whats the best way to set this up? I suspect I need to use STP but not really sure.

Hi, did you ever manage to do this ? I would like to do the same.
