Enable an instance of the ephemeral configuration database.
Starting in Junos OS Release 18.2R1, you can configure up to seven user-defined instances of the ephemeral configuration database. In earlier releases, you can configure up to eight user-defined instances. The order in which the instances are listed in the configuration determines the order of their priority when merging conflicting configuration statements from different instances into the configuration. The instances are listed in order from highest to lowest priority. In addition, user-defined instances of the ephemeral configuration database have higher priority than the default ephemeral database instance, which has higher priority than the static configuration database.
When you configure an ephemeral instance, you can specify its placement in the configuration by using the insert command instead of the set command.
The instance name must contain only alphanumeric characters, hyphens, and underscores, and it must not exceed 32 characters in length. In addition, starting in Junos OS Release 17.1R3, 17.2R3, 17.3R3, 17.4R2, and 18.1R1, the name of an user-defined instance cannot be default.
