Configure active-active setup for Artemis ActiveMQ

I did the active-active setup for artemis activemq with Jgroups protocol. I have configured 3 master and 3 slave servers with replication ha policy. I included all the servers in one group-name. From the documentation I am not able to check if I am doing proper active-active configuration. Please help me with this.

I have shared the broker.xml files of all 6 servers and test-jgroups-file_ping.xml here.

The observations are when all master and server is up and running, the logs says BridgeClusterConnection established. When any master goes down, the corresponding slave comes up. But when slave also goes down any other master does not become leader.

Please help me out.
