Hi  
I am using Elasticsearch 2.3.3  
I have machine A with following settings  
[cluster.name](http://cluster.name): jkaurelasticcluster  
discovery.zen.ping.multicast.enabled: true

And another machine B with following settings  
[cluster.name](http://cluster.name): jkaurelasticcluster  
discovery.zen.ping.multicast.enabled: true

Both the above machines are on same network but despite above settings the cluster through multi cast discovery doesnot form.

Are there any settings that I am missing ?

Multicast has been removed. Use unicast instead.

That is the best way.

If you really want multicast, then [https://www.elastic.co/guide/en/elasticsearch/plugins/current/discovery-multicast.html](https://www.elastic.co/guide/en/elasticsearch/plugins/current/discovery-multicast.html)
