GTM: Question about Sync-Group

Hello, we have two AFM devices in HA, we're gonna create DNS cache resolver on them. the question is should we create synchronization group between both active and standby to sync the listener or we shouldn't? juts noting that we're not using any GSLB, just recursion and security profile.

    A GTM listener is a LTM virtual server. So that would be synced with the configuration for HA you have.

     

    However, the other configuration will depend on what you are configuring. Besides the wide ip and other objects that the GTM syncs, it is normally configured also to sync the DNS zone files. If you don't sync, you need to configure in both the DNS settings in both units.
