Which Junos CLI command can save you from typing numerous delete and set commands after reconfiguring interfaces into logical units?

The command that effectively streamlines the process of reconfiguring interfaces into logical units is "replace pattern." This command allows you to specify a particular pattern that matches commands in the configuration, enabling you to replace or modify configurations based on that pattern.

For example, when you realize that a certain configuration needs to be changed across multiple logical interfaces, using this command allows you to update only the relevant settings without the need to input numerous delete and set commands manually. This significantly reduces the amount of repetitive work and minimizes the potential for errors associated with manual configuration changes.

By focusing on a specific pattern, you can efficiently manage configurations across similar entities or interfaces without extensive command input, making it a powerful tool in the Junos CLI for bulk modifications or adjustments.
