Each cluster must have a unique name, which is used to generate the +cluster's multicast group address. As long as no duplicate cluster names are +configured in one network segment, 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 packets are only delivered +to endpoints of the respective member nodes. + Adding Nodes to the Cluster --------------------------- -- 2.39.2
