<div dir="ltr">Adam --<div><br /></div><div>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.</div><div><br /></div><div>It sounds like my experience is worse than yours though?

Not 100% sure OVS was to blame, but since rebuilding and putting cluster communications on a dedicated NIC I haven't had any problems.<br />
