When you block communication between Zookeeper and the leader, the ZK client inside Solr will disconnect and its session will expire after the session timeout. At this point a new leader should be elected automatically. The default timeout is 30 seconds. You should be able to see the value in solr.xml property named "zkClientTimeout".
