Thanks Shawn. What i got is Circular replication is totally impossible & Solr fails in distributed environment. Then why solr documentation says that configure "REPEATER" for distributed architecture, because "REPEATER" behave like master-slave at a time. Can i configure SolrCloud on LAN, or i've to configure zookeeper myself. Please provide me any solution for LAN distributed servers. If zookeeper in only solution then provide me any link to configure it that can help me & to avoid wrong direction. Regards,Waqas
