title: Cluster in opendaylight
body: <p>I am trying to set up cluster according to this manual</p>
  
  <p><a href="https://docs.opendaylight.org/en/stable-magnesium/getting-started-guide/clustering.html" rel="nofollow noreferrer">https://docs.opendaylight.org/en/stable-magnesium/getting-started-guide/clustering.html</a></p>
  
  <p>But i also woukd  like to know how does it work.
  There is written that i choose which node/controller is leader and which will follow after 
   leader is down using member role - 1 - 2 in akka.config. 
  But in some work i have read it is using RAFT algorithm to choose/elect leader. Am i mixing it up somehow? 
  Can someone explain it to me please? </p>
