Enabling IS-IS Intelligent Convergence

Enabling IS-IS intelligent convergence can speed up IS-IS route convergence, thereby improving convergence performance.

Context

In a fault-triggered switching scenario where the local device receives a route from a single node, IS-IS intelligent convergence can be enabled to allow IS-IS to perform fast route convergence by using the fast convergence algorithm. This improves convergence performance.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS view is displayed.

  3. Run intelligent-convergence enable

    IS-IS intelligent convergence is enabled.

    In the same networking scenario, the convergence speeds of devices with the intelligent-convergence enable command configuration increase significantly, far higher than those of the devices without this command configuration. As a result, routing loops may occur. Therefore, exercise caution when you run this command.

  4. Run commit

    The configuration is committed.
