Conversely, how is it dangerous to have two two-node-clusters with different names sharing the intra-cluster network? In particular if one is in production and the other is for testing? And what about relative multicast-adresses for these two clusters? Can I safely use same multicast if the names are different or do I have to change? Ant rule in this case?
