How to connect 3 nodes without a switch?

[proitsupport]

In this tutorial, you have three nodes connected via 10Gbps ethernet without a switch using broadcast bridge mode. https://www.proxmox.com/en/training/video-tutorials/item/install-ceph-server-on-proxmox-ve

How was that physically cabled?

Thank you!

Thanks Tom! That is so cool! I had no idea that was possible.

I think that a cabling image should be added to the wiki

Is this configuration supporting multiple NIC for redundancy? You should also add STP to prevent loops if you close the Ring

In example, node1 to node2, node2 to node3 and node3 back to node1 but this latest cabling would form a loop and should be blocked by STP
