+Multiple Clusters In Same Network
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can create multiple clusters in the same physical or logical network. But,
+for this to work they all must have an unique cluster name, as its the
+identifier of the clusters multicast group address. If this prerequisite is
+fulfilled the different clusters won't interfere with each other.
+
+If multiple clusters operate in a single network it may be beneficial to setup
+an IGMP querier and enable IGMP Snooping in said network. This may reduce the
+load of the network significantly because multicast packages get only delivered
+to endpoints of the respective member nodes.
