Multinode Configuration Management

The config synchronization feature supports simple configuration management across an enterprise without requiring you to deploy the systems as a cluster. You synchronize a partial configuration from the running configuration on the source system to the running configuration on one or more target systems.

Disable gateway push config while using nSA config sync.
