This topic provides information on Multicast.

In systems with ephemeral containers, multicast is the preferred option. In cases where multicast routing is undesirable or not supported, unicast routing can be used.

Replace extend-client-config.xml with below code in digx-shared-libs.war/WEB-INF/classes
