instance (Ephemeral Database)

Syntax

Hierarchy Level

Description

Enable an instance of the ephemeral configuration database.

The order in which the configuration lists the instances determines 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.

Tip:

When you configure an ephemeral instance, you can specify its placement in the configuration by using the insert command instead of the set command.

Table 1 summarizes the maximum number of user-defined ephemeral database instances supported for different Junos OS variants and releases.
