Virtual Router to Support Multicast #9678

Open btzq opened 2 months ago

btzq commented 2 months ago
ISSUE TYPE
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?

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