Multicast
Consolidate multicast address and port settings in one location for easier maintenance. These settings must correlate to your physical network configuration (i.e. firewall, switch, and other network hardware matter) to ensure speedy and accurate communication across a cluster.
Each address and port combination represent a conversation that is made between different nodes. If they are not unique or correctly set, there will be a potential of unnecessary network traffic that may cause slower updates or inaccurate updates.
