recommended to enable STP?
STP has nothing to do with multicast as it's an Ethernet protocol.
It's developed to provide loop-free redundancy links to Ethernet-based
networks.
I can't imagine any legitimate use of STP within virtualized environment
except when BOTH a) you don't trust the person who manages VM's (like in
VPS providing) AND b) you provide more then one network interface to the
virtual machine.
Otherwise STP can be used to prevent traffic storm because of malicious
bridging of vNIC's inside VM.
