1. Transparent Cache

In this module we will implement all the configuration objects required for a transparent DNS cache on the BIG-IP.

Enabling a transparent cache offloads the back end DNS servers from responding to every query which frees resources on the servers.


Log into BIG-IP DNS using either the TMUI or webshell interface with credentials u:admin p:agility2020

Navigate to DNS ›› Caches ›› Cache List

then click the Create button to create a transparent cache with the following settings:

Setting Value
Name transparent_cache
Resolver Type Transparent


tmsh create ltm dns cache transparent transparent_cache
