Lightboard Lessons: F5 BIG-IP DNS (GTM) iQuery Protocol Overview

In this episode of Lightboard Lessons, I introduce iQuery, the F5 proprietary protocol utilized by BIG-IP DNS to exchange system configuration with other BIG-IP DNS systems and performance metrics with all other BIG-IP systems configured to do so.

    Question 1: on DC1 GTM you will see 1 conn : client:server + server :client as a new line for its own big3d, + 1 for each other client outside as a server:client so 1+2+6: 9. 9 right

    Q2: yes DC3 is isolated will act alone for that Dc only

     there is redundant command : bigip_add. According to K13312 if you do big3d_install the certs are exchanged as well . Done .

    big3d_add is redundant action if you do big3d_install. bigip_add you can use if you already know that you have the same big3d version on all systems.

     

    Think should be mentioned there on the board since confusion.

    Hi , I appreciate the feedback! I assume by big3d_add you mean bigip_add? If so, it could be redundant, but not necessarily so. If all the target systems have the latest big3d daemon, there's no need to run big3d_install at all.
