Thank you for the response. I even tried backing out open vswitch
completely - purging it from the system - and then manually reconfiguring a
single NIC without even a bridge and could not restore the multicast
communication. However, I reinstalled the single node I tried setting up
OVS on, deleted it from the existing cluster configuration on the other
system (which wasn't reloaded), and re-added it and its working again.
Nothing has changed on the switch or the other node. It seems for some
reason as soon as I installed OVS it broke multicast for that node
completely and the only way I could restore it was to reinstall.
It sounds like my experience is worse than yours though? In your case you
still have OVS installed and it is still working?
