How do you configure multi VLAN configuration into a single configuration statement?

The correct approach to configuring multiple VLANs in a single configuration statement is to enclose every VLAN inside square brackets. This method is supported by various network configuration interfaces, including those found in Juniper devices. It allows you to clearly define a set of VLANs that are to be treated together, which is particularly useful when applying settings uniformly across multiple VLANs.

Using square brackets helps to avoid ambiguity in parsing the configuration statement, ensuring the device correctly interprets the configuration as intended. This syntax allows for a clean and organized presentation, making it easier to read and maintain network configurations.

Other options may suggest various methods of separating VLAN IDs, but they do not align with the standard syntax used in Juniper's configuration. This reinforces the understanding that specific formatting conventions are vital for correct network device configurations.
