iRule for forward WideIP to external BIGIP DNS

Boban

Hi all,

 

In F5 BIGIP DNS under DNS-GSBL-WIdeIP there is option/tab iRule. I would like to create iRule for the WideIP (NAPTR and A).

 

Scenario: DNS Q test1.test.com(NAPTR) comes to PROD-BIGIP-DNS which has WideIP test1.test.com(NAPTR) and inside this WideIP I need iRule which will just forward ONLY this wideIP to other LAB-BIGIP-DNS listener IP address.

 

NOTE: LAB-BIGIP DNS-listener is configured under PROD-BIGIP as Server/virtual server(Generic Host) because of optimization reasons.

 

Regards,

Boban

BTW iRule under WideIP like this below is not working, so anybody have idea what should be corrected?

 

when DNS_REQUEST {

  virtual LAB-BIGIP-DNS-LISTENER-IP

}
