This assumes you are running Proxmox 8.2 and that the line source /etc/network/interfaces.d/*
is at the end of the interfaces file (this is automatically added to both new and upgraded installations of Proxmox 8.2).
This changes the previous file design thanks to @NRGNet for the suggestions to move thunderbolt settings to a file in /etc/network/interfaces.d it makes the system much more reliable in general, more maintainable esp for folks using IPv4 on the private cluster network (i still recommend the use of the IPv6 FC00 network you will see in these docs)
This will result in an IPv4 and IPv6 routable mesh network that can survive any one node failure or any one cable failure. Alls the steps in this section must be performed on each node
