iRule to determine what pool the VIP should send traffic to?

I'm looking to create an iRule that would look at the status of a pool and send VIP traffic to it.

 

 

For example:

 

Pool 1-1.1.1.1

 

Pool 2- 1.1.1.2

 

 

 

 

 

1. I connect to VIP (ex: testing.mysite.com)

 

2. If pool 1 is down, send traffic to pool 2

 

3. And the same for the reverse, if pool 2 is down, send traffic to pool 1

 

 

 

Any assistance would be greatly appreciated - Thanks!

    Check out lb::server with activemembers query for a good starting point.

    Hope this helps,

    You can also use a single pool with priority group activation. You can check the LTM config guide for your version for details.
