Managing GSLB iRules

How do I manage GSLB iRules in BIG-IQ?

iRules® allow you to manipulate and manage the application traffic in your GSLB domain. Using iRules scripting syntax, you can customize how you intercept, inspect, transform, and direct inbound or outbound application traffic.

You can view the GSLB iRules configured for the DNS sync groups you manage by navigating to Configuration > DNS > GSLB > iRules . From there, click an iRule to view it, or click Create to set up a new one.

Create a GSLB iRule

You create a GSLB iRule so that you can manage the virtual servers that host the content of your domain.
  1. At the top of the screen, click Configuration, then, on the left, click DNS > GSLB > iRules .
    The screen displays the list of iRules defined on this device.
  2. Click Create.
    The New iRule screen opens.
  3. Type a Name for the GSLB iRule.
  4. In the Body field, compose the script sequence that defines the iRule.
    For guidance on creating an iRule, consult the AskF5 Knowledge Base. You can search the AskF5 website for iRules documentation that provides an overview of iRules, lists the basic elements that make up an iRule, and shows some examples of how to use iRules.
  5. Click Save & Close.
    The system creates the new iRule and adds it to the list of iRules.
