Create a separate LAN for cluster replication traffic

How can I create a separate LAN specifically for cluster replication traffic?
This is fairly simple from a Domino perspective:
  1. First, set up the LAN. Usually, a simple switch will suffice if there are no routing issues to overcome.

  2. Put the cluster servers on the LAN via a second network card.

  3. Then add a new port to the Domino server's server documents. Many people call it "CLUSTER."

  4. Add the appropriate IP address and named network. Do not make it the same DNN as the regular TCP/IP port.

  5. Now add a few notes.ini variables. You need to set up the variables for the TCP/IP addresses (CLUSTER_TCPIPAddress=0,192.168.1.25:1352 and OtherPortName_TCPIPAddress=0,10.0.0.25:1352). That tells the Domino server which port is listening on which IP.

  6. Add the new CLUSTER port as well, with a "CLUSTER=TCP,0,15,0" in the ports area of the notes.ini.

  7. Then add the CLUSTER port to the enabled ports line of the notes.ini.

  8. Finally, set the variable "Server_Cluster_Default_Port=CLUSTER."

That should get you going on a private LAN, or another port on your public LAN for that matter.
