Need Help Configuring Multicast Routing on Hyper-V Environment for RTP Streams.

Question

Hello, I'm relatively new to network configuration on Virtualization Environment, and I'm currently facing an issue with setting up multicast streaming in my Hyper-V environment. Here's the scenario: I have a streaming device connected to the External Network, and I have several Hyper-V VMs on the Internal Network that are supposed to receive multicast RTP streams from the streaming device. However, I'm encountering difficulties as the Internal VMs are not receiving the multicast streams. If VMs belonging to the Internal Network, VMs cannot receive multicast streams.

• If VMs belonging to the External Network, VMs can receive multicast streams.

Could someone guide me through the necessary network configuration settings to ensure proper multicast communication between the External Network (streaming device) and the Internal VMs in Hyper-V?

Here is graphical representation of the issue details of my setup:

If anyone has experience with this kind of setup or can provide step-by-step instructions, I would greatly appreciate your help. Additionally, if there are any specific settings or considerations, I should be aware of, please point them out. Thank you in advance for your assistance!

Answer 1

I don't think I understand your goals. This is the intended design of the internal and private virtual switch configurations. The internal switch provides a network that the host and virtual machines can access, but has no connection to the physical network. The private switch is the same, but does not allow presence of the host. You could build a VM with presence on both the external switch and the internal switch and use routing software in it to forward the multicast messages that it receives from the external switch network to the internal switch network.
