Hi. To disable multicast, you need to change "ipFinder" in "discoverySpi" configuration to "TcpDiscoveryVmIpFinder" and specify the list of node's addresses.
Check the link below for the configuration example: https://apacheignite.readme.io/docs/tcpip-discovery#section-static-ip-finder Regards, Igor -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
