Virtual Router to Support Multicast

[btzq]

ISSUE TYPE

• Improvement Request

COMPONENT NAME

Virtual Router

CLOUDSTACK VERSION

4.19.1.1

CONFIGURATION

OS / ENVIRONMENT

SUMMARY

Currently Cloudstack Virtual Router doesnt support Multicast from external networks (eg. Private Gateway).

In our case, our customers require multicast support because they decode Stock Market Feeds from the Stock Exchange. And Majority Stock Exchange distributes market feeds in ITCH format, which is Multicast.

In order to overcome this limitation now, we had to resort to VNF + L2 Networks.

I also have a curious question, if Cloudstack VR does not support multicast, then why is there a UDP Protocol option in the Network ACL Rules?

STEPS TO REPRODUCE

EXPECTED RESULTS

For VR to support multicast natively

ACTUAL RESULTS

VR does not support multicast at the moment.

I also have a curious question, if Cloudstack VR does not support multicast, then why is there a UDP Protocol option in the Network ACL Rules?

UDP can be used for single destinations as well. DNS or TFTP for instance.
