Description
##### 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.

Contributor guide
Research direction
The issue identifies CloudStack's Virtual Router and requests native multicast support for external networks, but names no files, tests, commands, or entry points. Start by locating the Virtual Router networking implementation and existing protocol or routing tests. Done means multicast traffic works natively through the Virtual Router for the described external-network use case.
