Hi Paolo,
With multicast IP finder you should have a separate multicast group address
for each topology. It can be configured like this:
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<bean
class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
<property name="multicastGroup" value="228.1.2.5"/>
</bean>
</property>
</bean>
</property>
All nodes with the same group address will join the same topology, while
nodes with different group addresses will never discover each other.
