|Deploying GemFire XD / Configuring Discovery Mechanisms|
You configure multicast discovery by specifying the mcast-address and mcast-port properties.
To start an embedded GemFire XD peer with multicast discovery, specify the multicast address and port as options in the JDBC peer client connection URL, or in the property object that you send in the FabricServer.start() method. For example:
To start a GemFire XD server with multicast discovery from a command prompt or terminal window, add the multicast properties directly to the gfxd command. For example:
gfxd server start -mcast-address=address -mcast-port=port
