You have two different Sync configuration on F5 DNS:

  • F5 DNS sync group where DNS and BIND configuration can be synced between all F5 DNS members of the group look under DNS >> Settings >> GSLB >> General (Configuration Synchronization) where you can set the group name and what to Synchronize
    • https://support.f5.com/csp/article/K13734
    • https://support.f5.com/csp/article/K13690

 

  • F5 Device Group and HA are used more for LTM and other modules that need to failover this will sync up LTM based configuration and will work in an Active/Standby for each Traffic Group configured. Recommend you do not do this for F5 DNS/GTM as better to have all devices Active and failover is not required as DNS is already a fault tolerant protocol.
