Good morning, In general, you shouldn't need to do anything special at the switch level, but of course, that depends on your switch. Using fairly normal (unmanaged) switches, I've been fine. Here is my note to myself on multicast in OpenAIS: This is the multicast address used by OpenAIS. Avoid the '224.0.0.0/8' range as that is used for configuration. If you use an IPv6 address, be sure to specify a 'nodeid' in the 'totem' directive. HTH!
