[Linux-cluster] Can same cluster name in same subnet?

[Gianluca Cecchi]

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?

Thanks,
Gianluca
