Hello,

I’m facing an issue with multicast traffic in my Hyper-V environment and would appreciate some insights.

I have IGMP snooping enabled, and I’ve noticed the following behavior:

Multicast works when VMs are on different hosts.Multicast also works when VMs are on different logical switches.However, multicast does not work when VMs are on the same host or using the same logical switch.

Could someone help explain why multicast is not functioning in the latter scenario? Are there specific configurations or settings I should check in Hyper-V or SCVMM that could affect multicast traffic when VMs are on the same host or logical switch?

Thank you for your assistance!
