Add LTM two boxs ( HA ) on F5 GTM

Amr_Ali It should be a matter of ensuring the GTM hardware has the LTM license active and provisioned which will require a reboot of the GTM. Typically it's recommended that the GTMs have their own IP that they accept DNS queries on and not share that with the LTM portion of the configuration other than the management IP itself. You would have HA configured for LTM but only have the sync group for GTMs configured so that the GTMs respond independetly of each other and the LTMs work as physical hardware backups for the other. It is not generally recommended that you combine GTM and LTMs on one platform but it can be done. The reason for this is because the GTMs tend to sit on your edge and the LTMs tend to sit in a higher security area but that doesn't mean you can't do it.
