title: Unable to form cluster of 2 nodes in distributed cache using Infinispan
body: <p>There are two scenarios as mentioned below.</p>
  
  <p><strong>First Scenario:</strong></p>
  
  <p>Node1: 192.168.<strong>69</strong>.201</p>
  
  <p>Node2: 192.168.<strong>69</strong>.202</p>
  
  <p><strong>Second Scenario:</strong></p>
  
  <p>Node1: 192.168.<strong>69</strong>.201</p>
  
  <p>Node2: 192.168.<strong>68</strong>.203</p>
  
  <p>Cluster is formed successfully in the first scenario but not in the second one. I used TCP protocol as mentioned in the below xml:</p>
  
  <pre><code>&lt;config xmlns="urn:org:jgroups"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="urn:org:jgroups file:schema/JGroups-3.2.xsd"&gt;
      &lt;TCP
              bind_addr="${jgroups.tcp.address:192.168.68.201}"
              bind_port="${jgroups.tcp.port:7800}"
              loopback="true"
              ...
               /&gt;
  
      &lt;MPING bind_addr="${jgroups.bind_addr:192.168.68.201}" break_on_coord_rsp="true"
             mcast_addr="${jgroups.mping.mcast_addr:228.2.4.6}"
             mcast_port="${jgroups.mping.mcast_port:43366}"
             ip_ttl="${jgroups.udp.ip_ttl:2}"
             num_initial_members="3"/&gt;
      ...
      ...
  &lt;/config&gt;
  </code></pre>
  
  <p>192.168.68.201 was replaced by respective IP address at a particular node.</p>
