title: What is the difference between VSE version and Core version of Vyatta AMI
body: <p>I create two instances on AWS, both of them are about Vyatta AMI, one is VSE6.7 version, and the other is Vyatta Core version.</p>
  
  <p>I want to use HA cluster function, if I use the VSE6.7 AMI, I will get the error message, <code>Configuration path: [cluster] is not valid. Set failed</code>, by typing "set cluster interface tun00" in configure mode.</p>
  
  <p>But it works on Vyatta Core version.</p>
  
  <ol>
  <li>What is the difference between VSE AMI and Core AMI?   </li>
  <li>Should I choose Vyatta Core AMI for cluster function?</li>
  <li><p>Is it supported on<br>
  VSE AMI?</p>
  
  <p>Thanks for your support :)</p></li>
