HyperV Multicast going to every VM

Copper Contributor

Hi All,


We are attempting to move some audio processing servers into our SCVMM Stack. To date its working well, however i have noticed that once i enable multicast it starts flooding every VM that is on the same Logical Switch.


I have trawled the internet for a few weeks and i cant really find if or how to prevent this.


We are running Dell R740s with Windows 2019 DC Core. I have attempted to use both Nic teaming and embedded team wtih SRV but nothing i do will resolve this. 


I have also read that enabling mac spoofing might help, but hasnt.


Are there any other settings i can look at?


Cheers Matt.
