STP, RSTP or MSTP?

[Sven Jörns]

With our Ubiquiti switches you can set the Spanning Tree Protocol in three different variants. On the Proxmox page you can't set anything via the GUI. But in the configuration files it is. The Ubiquiti switches have set MSTP as default value, which I left as it is. If I now have a trunk connection with different VLANs, what would be the best setting for the Linux Bridge?

Hi,

Spanning Tree Protocol is only used in L2 network, normally VLAN networks are connected over L3(routed).
So as long you do not add a second nic without using it as a bond to the vmbr STP is not needed.
Anyway, Linux Bridges support only STP.
