Setting up standard VIPA

Edit online

Ubuntu 22.04 LTS LPAR mode z/VM guest

To set up VIPA you must create a dummy device, ensure that your service listens to the IP address, and set up routing to it.

Procedure

Follow these main steps to set up VIPA in Linux®:
  1. Create a dummy device with a virtual IP address.
  2. Ensure that your service (for example, the Apache web server) listens to the virtual IP address assigned in step 1.
  3. Set up routes to the virtual IP address, on clients or gateways. To do so, you can use either:
    • Static routing (shown in the example of Figure 1).
    • Dynamic routing. For details of how to configure routes, you must see the documentation that is delivered with your routing daemon (for example, zebra or gated).
