Usage Guidelines

Usage Scenario

After an IS-IS process is configured in the system view, to make the IS-IS protocol function normally, enable IS-IS on an interface to associate the interface with the IS-IS process.

Prerequisites

An IS-IS process has been enabled using the isis command in the system view.

Precautions

An interface can be associated with only one IS-IS process.
