    Unable to join cluster

    Ruchi Newbie

      I have configured TreeCache on 4 nodes-

      Node A : 10.164.32.30
      Node B : 10.164.32.55
      Node C : 10.164.32.29
      Node D : 10. 164.33.51

      Node A, B, C being on same network are able to join the cluster. However Node D is unable to join them and is creating a seperate cluster on its own.

      When i check route from Node A to Node B using command "tracert 10.164.32.55", i get the following -
      Tracing route to 10.164.32.55 over a maximum of 30 hops
      1 <1 ms <1 ms <1 ms 10.164.32.55
      Trace complete.

      Tracing route to 10.164.33.51 over a maximum of 30 hops
      1 4 ms <1 ms <1 ms 10.164.32.5
      2 <1 ms <1 ms <1 ms 10.164.33.51
      Trace complete.


      Basically there is a switch(10.164.32.5) in between.

      Can you tell me whats the problem. What do i need to change in my treecache/jgroups configuration

          Use a MERGE2 protocol

            I tried using MERGE2, but its not working. Here is my configuration -



            <UDP bind_addr="10.164.32.30" ip_mcast="true" loopback="true"/>
            <PING timeout="2000" num_initial_members="3"

            <FD_SOCK/>
