Next, we are going to define a UDP profile. A UDP profile will instruct the BIG-IP DNS listener on how to handle UDP traffic. The DNS profile we created earlier instructs the BIG-IP DNS on how to process the layer 7 data inside of the UDP packets, but not how to handle the UDP protocol itself. For more information on UDP profiles, please refer to the link below.
It is required to complete the following task on both gtm1.site1 and gtm1.site2
On gtm1.site1 navigate to: DNS ›› Delivery : Profiles : Protocol : UDP
On gtm1.site2 navigate to: DNS ›› Delivery : Profiles : Protocol : UDP
Create a new UDP profile as shown in the following table:
TMSH command for both gtm1.site1 and gtm1.site2:
