Well, I got some good news. I was able to get a successful multicast going tonight. I am not 100% sure of what fixed it. I did several things.
Not in particular order:
Updated FOG to trunk
Disabled IGMP snooping from the switches
Made a change to CentOS as seen
here that has to do with routing (honestly don’t think this helped)
Added 232.168.1.0 for FOG_MULTICAST_ADDRESS (it wouldn’t work without that)
I plan to do more tests to really make sure it is working tomorrow and the following days. I will keep this updated if anything substantial changes.
Thank you to everyone.
