Configuration Synchronization
About configuration synchronization
Configuration synchronization ensures the rapid distribution of BIG-IP® DNS settings to other BIG-IP systems that belong to the same BIG-IP DNS synchronization group. A BIG-IP DNS synchronization group might contain both BIG-IP DNS and BIG-IP® Link Controller™ systems.
Configuration synchronization occurs in the following manner:
- When a change is made to a BIG-IP DNS configuration, the system broadcasts the change to the other systems in the BIG-IP DNS synchronization group.
- When a configuration synchronization is in progress, the process must either complete or timeout, before another configuration synchronization can occur.
About NTP servers and BIG-IP DNS configuration synchronization
The Network Time Protocol (NTP) servers that BIG-IP DNS references ensure that each system in a BIG-IP DNS synchronization group is referencing the same time when verifying configuration file timestamps.
